The Consumer Financial Protection Bureau is a federal agency created specifically to handle complaints like yours, and filing with them is free, takes about ten minutes, and legally requires the company you are complaining about to respond — usually within 15 days. It will not put money directly in your pocket the way a lawsuit can, but it creates an official federal record, often gets fast results because companies do not want unresolved CFPB complaints on file, and can be filed alongside every other option on this list, not instead of them.
Start at consumerfinance.gov/complaint
Go directly to the CFPB's own complaint portal. Select "Debt collection" as the product type, then choose the issue category that most closely matches your situation — options include things like "threatened to take legal action they cannot take," "called repeatedly or continuously," and "contacted me about a debt I do not owe." The form saves your progress automatically, so you do not need to finish in one sitting.
Write a clear, factual narrative
The CFPB gives you space to describe what happened in your own words. Stick to specific facts: dates, times, what was said, how many times they called, whether you had already sent a cease and desist or validation letter. Avoid generalizations like "they harassed me constantly" in favor of concrete detail like "they called four times between 7 and 8 AM over two days despite a cease and desist letter sent on [date]." Specific narratives get taken more seriously and are more useful if the case ever escalates to an attorney.
Attach your documentation
If you have a copy of a cease and desist or debt validation letter you sent, certified mail receipts, call logs, or voicemails, reference them in your narrative even if you cannot attach every file. The CFPB does allow document uploads as part of the complaint process — include anything that supports your timeline.
What happens after you submit
The CFPB forwards your complaint directly to the company, which is generally required to respond within 15 days. You will get updates through the CFPB's online portal, and the company's response becomes part of the public record (with your personal details redacted) in the CFPB's consumer complaint database. Many collectors resolve complaints quickly once a formal CFPB complaint is on file, simply because a pattern of unresolved complaints draws regulatory attention they would rather avoid.
File with your state Attorney General too, if it applies
Many states have their own consumer protection laws that go further than the federal FDCPA, and your state Attorney General's office can investigate independently of the CFPB. Filing both is not redundant — they are separate systems that can each apply pressure in different ways, and neither prevents you from also pursuing a lawsuit if the violations are serious enough.
