As of 13 August 2026, AI can complain about a debt collection agency.

What to actually do

1. Hand it to a person

   The route this page recommends

   A person who owns the outcome does this end to end, worth it when the failure is dear.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open the agency's latest letter, your payment records and any earlier messages, then make a timeline of contact dates, amounts, reference numbers and what was said.
   2. Redact unnecessary personal information from the documents, keeping enough of the reference number and correspondence to identify each item.
   3. Paste the timeline, the relevant extracts and your desired outcome into a chatbot with the copyable prompt, and answer its questions before asking for the final draft.
   4. Compare every sentence in the draft against the original letters, your bank or payment records and your timeline, correcting any unsupported amount, date, quotation or allegation.
   5. Check the suggested complaint route against the agency's own complaints information and the relevant official UK source, and remove any legal conclusion you cannot verify.
   6. Send the complaint through the agency's stated channel, attach the relevant evidence, keep a copy of everything sent and record the date of sending.
   7. If the response is inadequate or the matter is serious, take the records and draft to a solicitor or an appropriate debt-advice or complaints professional before escalating.

   Prompt

   Help me prepare a complaint about a UK debt collection agency. This is not professional advice. Do not decide that the debt is legally unenforceable, do not invent facts, rules, deadlines, account details or evidence, and do not present uncertain points as facts.
   
   Use only the information I provide. First identify any missing facts that materially affect the complaint, including:
   - the agency's name and contact details
   - the original creditor, if known
   - the account or reference number, with sensitive parts redacted
   - what the agency claims I owe
   - what I dispute and why
   - the dates of letters, calls, payments and other relevant events
   - how the agency contacted me and how often
   - copies or accurate extracts of relevant correspondence
   - what I have already asked the agency to do
   - the outcome I want
   
   Then produce:
   1. A short chronology, clearly marking anything uncertain.
   2. A list of the evidence I have and the evidence still needed.
   3. A calm, factual complaint letter addressed to the agency, with a subject line, numbered issues, specific requests, a request for a written response, and no unsupported legal claims.
   4. A separate list of statements in the letter that I must check against my records before sending.
   5. A separate section called 'Escalation to check' naming the official UK source or complaints route I should check for this type of firm and issue. Do not provide a route unless the facts support it, and say when you cannot tell.
   6. A short version suitable for an online complaint form.
   
   Keep the tone firm and non-threatening. Do not include unnecessary personal data. Use placeholders such as [AGENCY NAME] and [REFERENCE] where details are missing. Ask me questions before drafting if a missing fact could change the complaint.

   Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.
