DEBT DISPUTE AND REQUEST FOR ACCOUNT EVIDENCE
IMPORTANT LEGAL, JURISDICTION AND FORMALITY WARNING
This fictional letter is an educational worked example, not legal advice, a finding that a debt is unenforceable, a request to erase accurate information or a promise that collection activity must stop. It assumes an unsecured consumer account and a resident of England and Wales. The creditor’s assignment, agreement, statements, default process, limitation position, regulatory rules and court procedure must be checked against the actual evidence. A dispute letter does not automatically stop interest, enforcement, limitation or a court deadline, and it is not a defence to a claim form. The sender should obtain independent debt advice before withholding payment, admitting a balance, making a settlement offer or signing a statement of truth.

Rivermark reference: RR-581204 Original creditor described in your letters: Calderline Retail Bank plc Account said to end: 9031
Subject: Formal dispute of ownership, balance and payment allocation
1. Reason for dispute
I dispute the sum that Rivermark Recoveries Limited has demanded under reference RR-581204. Your letter of 2 November 2026 demands £2,914.60, described as a balance acquired from Calderline Retail Bank plc. I do not admit that Rivermark owns the account, that the account ending 9031 belongs to me, that the balance is £2,914.60, or that the amount is presently enforceable. I am willing to investigate an account properly identified by contemporaneous records, but I will not make a payment merely to end repeated demands.
My own records show that I held a Calderline retail credit account ending 9031 and made regular payments until January 2025. However, the last statement I retained, dated 31 January 2025, showed £1,246.80, not £2,914.60. I paid £160.00 on 4 February 2025 and £160.00 on 4 March 2025 by standing order. My bank records show both payments leaving my account. I then received a Calderline email on 18 March 2025 stating that a payment arrangement of £160.00 per month had been noted and that the next review would be in June. Rivermark’s demand does not credit either payment and gives no calculation explaining how the balance increased by £1,667.80.
The disputed difference is calculated as £2,914.60 demanded less £1,246.80 shown on the last retained statement, which equals £1,667.80. The two uncredited payments of £160.00 each must also be traced in the ledger, but they do not alter the £1,667.80 increase between the two stated balances. These figures are not an assertion that the January statement is necessarily the final account position; they identify the evidence that must be reconciled. Please do not treat the arithmetic in this paragraph as an admission of the principal or any contractual interest.
2. Chronology
Calderline opened the retail account on 12 June 2021 for purchases from its North Quay Home Store. I made monthly payments by standing order from July 2021 through January 2025. A statement dated 31 January 2025 showed a purchase balance of £1,246.80, an interest entry of £18.40 and a payment credit of £160.00, resulting in the displayed closing balance of £1,246.80 after the statement’s other entries. I have not found the original agreement or every earlier statement, so I ask for copies rather than presenting an incomplete history as conclusive.
On 4 February 2025 my bank paid £160.00 to Calderline under standing-order reference CA-9031-0402. On 4 March 2025 my bank paid a further £160.00 under reference CA-9031-0403. The payments were not returned. On 18 March Calderline’s customer service email recorded that I was on a £160.00 monthly arrangement. I asked for a current statement on 3 June because the account was not visible in the online portal. Calderline’s automated reply said the account had moved to a “specialist team” and supplied no balance.
Rivermark’s first letter, dated 14 August 2026, said that Calderline had assigned the account on 30 June 2025 for £2,106.80. That letter demanded £2,106.80 and named an original account number ending 1183, not 9031. I wrote on 21 August asking Rivermark to correct the identifier and provide evidence of assignment. Rivermark’s second letter dated 15 September used the ending 9031 but demanded £2,674.60. Its third letter of 2 November demanded £2,914.60 and added £240.00 described as “recovery costs”, without identifying a contractual or statutory basis.
I have not received a court claim form, judgment, warrant or notice of enforcement from Rivermark. I have not consented to service by email. If formal proceedings are issued, I will deal with them by the required court process and will not assume that this letter replaces an acknowledgment of service or defence. If Rivermark has instructed an enforcement agent or has obtained a judgment, please provide the court, claim number, date and legally permitted notice rather than describing an ordinary demand as enforcement.
3. Evidence requested
Please provide, securely and with unnecessary personal data redacted:
1. the agreement or application relied upon, including the terms in force when account 9031 was opened and any variation relied upon; 2. a complete transaction statement from opening to the present, showing purchases, payments, interest, default fees, other charges, credits and the running balance; 3. records allocating the £160.00 payment dated 4 February 2025 and the £160.00 payment dated 4 March 2025, including any reversal or suspense account entry; 4. the notice of default, any notice required before termination or enforcement, and evidence of how and when it was served; 5. the deed, notice or other document on which Rivermark relies to show assignment, together with the date of assignment and the balance assigned; 6. an explanation for changing the account identifier from ending 1183 to ending 9031 and confirmation that no other person’s account has been mixed with mine; 7. the contractual or statutory basis for £240.00 recovery costs and every later interest or fee; and 8. confirmation of the current owner, data controller, correspondence address and whether any court judgment exists.
I am not asking Rivermark to disclose another customer’s data or commercially irrelevant material. It may use a secure portal or postal copies. I will provide reasonable identity verification through a secure channel; I will not send a full identity document to an unverified email address. If Rivermark says a document cannot be supplied, identify it, explain why and provide a reliable summary sufficient to test the demand.
4. Requested account correction and interim position
Please place the account on hold for investigation and mark the balance as disputed. Please ask any collection agent to communicate only in writing while the identifier, payments and ownership are checked. This request is not a claim that Rivermark is legally obliged to cease every lawful activity, and it does not prevent Rivermark from serving a formal notice in the prescribed manner. I ask that no new fee or adverse data entry be based on the disputed £2,914.60 while the complaint is unresolved, subject to the correct legal and regulatory position.
If your investigation confirms that account 9031 is mine, please issue a corrected statement. On the present evidence, that statement should credit payments of £320.00 and remove any charge unsupported by the agreement or applicable law. It should separately show the principal, contractual interest, default charges, payment dates, allocation method, assignment balance and any later adjustment. Please do not simply replace £2,914.60 with a new rounded figure.
I do not presently offer a token payment or settlement because doing so could be misunderstood as an admission while ownership and amount remain unresolved. I have set aside the disputed correspondence and will consider a sensible payment or affordable arrangement after receiving evidence and independent debt advice. I will continue to pay priority household liabilities and will not use this dispute as a reason to stop an unrelated account.
5. Complaint and escalation
Please treat this as a formal dispute and complaint. Acknowledge it within 14 days and provide the evidence and a reasoned response within 30 days, or tell me what specific information is still needed and when a final response will be issued. If Rivermark is acting for a regulated lender or is itself within the Financial Ombudsman Service’s jurisdiction, please provide the correct complaint route and explain whether a final-response letter will be issued. I do not assume that the Financial Ombudsman Service has jurisdiction over every debt purchaser or every historic act; eligibility must be checked against the businesses, dates and subject matter.
If Rivermark cannot substantiate ownership and the balance, I request written confirmation that collection of the disputed sum will cease, inaccurate data will be corrected with any recipient, and the file will be closed or returned to the owner. If the evidence establishes a smaller balance, I ask that the corrected balance be stated and that a reasonable payment discussion take place without adding unsupported fees. If the complaint remains unresolved, I may contact the Information Commissioner’s Office about inaccurate personal data, an applicable ombudsman or regulator, a free debt adviser, or the County Court. None of those routes is guaranteed to accept the matter, and I will check their deadlines separately.
Please preserve the assignment records, account statements, payment ledger, call recordings, letters, data-supply records and complaint notes. Please correspond with me at 29 Hazelbourne Street, Newcastle upon Tyne NE6 2LA and peter.armitage@example.test. Nothing in this letter is an admission, waiver, acknowledgment for limitation purposes, consent to email service, or promise that no payment will ever be due. I reserve the right to amend this dispute when complete records are supplied.
Yours faithfully,
Peter Julian Armitage
