Guide
File at consumerfinance.gov/complaint or by phone. A complaint is not a lawsuit and does not pause any deadline — your validation window and your answer deadline keep running. File it alongside your written dispute, never instead of it.
What to write: dates, not adjectives. 'On March 3, 5 and 6, the collector called 9 times about account ending 4417' beats three paragraphs about harassment. Attach your call log and a copy of any letter you sent — the same record the kit's violation log formats for you.
What happens: the CFPB forwards the complaint to the company, which generally must respond within about 15 days. Responses are not always remedies — but companies answer the CFPB with a seriousness they rarely show a phone call, and the complaint becomes part of the public record regulators use when they bring enforcement cases (debt collection drew roughly 387,000 complaints in 2025, the second-largest category the CFPB tracks).
Also file with: your state attorney general's consumer-protection office, and — for original creditors — the issuer's own regulator channel via the CFPB as well. In states whose statutes cover original creditors (California, Texas, Massachusetts, Maine, Florida), the AG complaint carries statutory weight of its own.
One payment. Every stage of the road, and the deadline tables for all 50 states — every number with its law cited. No account, no subscription — and the free checker above stays free whether you buy or not.
DebtDecoded is education, not a law firm. If the checker points you to a free route — legal aid, a lawyer who fights debt collectors, a nonprofit counselor — take it. We would rather lose the sale than sell you the wrong tool.
