You can file a complaint against a bank directly with the Consumer Financial Protection Bureau (CFPB) at consumerfinance.gov/complaint, and the bank is generally expected to respond within 15 calendar days. But before going to a federal agency, starting with the bank itself often resolves issues faster. Here’s how to handle both paths, plus how to escalate if neither works.
Start With the Bank Directly
Most banks have a formal complaint resolution process that kicks in once you put your issue in writing. Phone calls to customer service can solve simple problems, but written complaints create a paper trail and trigger internal timelines the bank has to follow. Banks typically acknowledge written complaints within 15 days and aim to fully resolve issues that don’t require an investigation within 30 days. More complex complaints that involve an on-site investigation may take up to 45 days.
Call the bank’s customer service line first and ask to escalate to a complaint resolution officer or the executive office. If the frontline representative can’t help, request the name and contact information of the person or department that handles formal complaints. Then follow up in writing, either by email or certified mail, so you have proof of when the complaint was sent.
In your written complaint, include your full name, account number, a clear description of the problem, the dates of any relevant transactions, and what resolution you’re seeking. Attach copies (never originals) of any supporting documents: statements, receipts, screenshots of errors, or records of previous calls including the representative’s name and the date you spoke. Being specific about what went wrong and what you want the bank to do gives the complaint handler something concrete to work with.
File With the CFPB
If the bank doesn’t resolve your issue, or if you want a federal agency tracking the complaint from the start, submit one through the CFPB’s online portal at consumerfinance.gov/complaint. The CFPB handles complaints about checking and savings accounts, credit cards, mortgages, auto loans, student loans, money transfers, and debt collection tied to banking products.
The process works in five steps. First, you submit your complaint online, describing what happened and what product or service is involved. The CFPB then routes your complaint directly to the bank. The bank reviews the issues you raised, communicates with you as needed, and responds. Companies generally respond within 15 calendar days, though in some cases the bank will notify you that its response is in progress and provide a final answer within 60 days. Once the bank responds, you get 60 days to review the response and provide feedback on whether the issue was resolved to your satisfaction.
Your complaint (with personally identifying information removed) gets published in the CFPB’s public Consumer Complaint Database. This happens either after the company responds or after 15 days, whichever comes first. If you consent, the CFPB will also publish your description of what happened. That public visibility gives banks an incentive to take complaints seriously.
If the CFPB determines another government agency is better positioned to handle your complaint, it will forward your submission and let you know.
Figure Out Your Bank’s Federal Regulator
The CFPB is often the best starting point for consumer complaints, but banks also answer to a primary federal regulator based on how they’re chartered. Filing with the right regulator can add pressure, especially for issues the CFPB may redirect.
National banks and federal savings associations are regulated by the Office of the Comptroller of the Currency (OCC). You can search for your bank on the OCC’s site at helpwithmybank.gov to check whether it falls under their oversight. If your bank doesn’t appear there, it’s likely a state-chartered bank or a credit union.
State-chartered banks are overseen by one of two federal agencies. If the bank is a member of the Federal Reserve System, the Federal Reserve Board supervises it. If it’s not a Fed member, the FDIC handles oversight. State-chartered banks also answer to their state banking regulator, which you can find through the Conference of State Bank Supervisors website. Credit unions fall under the National Credit Union Administration (NCUA) rather than any of these banking regulators.
If you’re unsure which category your bank falls into, contact the bank and ask who its primary regulator is. They’re required to know.
What to Include in Any Complaint
Whether you’re filing with the bank, the CFPB, or a federal regulator, strong complaints share the same ingredients:
- Account details: Your name, account number, and the type of account or product involved.
- Timeline of events: Specific dates of transactions, errors, or conversations with bank staff. Vague descriptions like “a few weeks ago” weaken your case.
- Documentation: Copies of bank statements, fee disclosures, loan agreements, receipts, emails, or chat transcripts that support your version of events.
- Record of prior attempts: Names of representatives you spoke with, dates of calls, reference or case numbers the bank provided, and any written responses you received.
- Desired resolution: State clearly what you want: a fee refund, a corrected credit report entry, reversal of a transaction, or some other specific outcome.
Keeping organized records from the beginning makes every stage of the process easier. Save confirmation emails, take screenshots, and note the date and time of every interaction.
File a State-Level Complaint
Your state’s attorney general office and state banking department both accept consumer complaints against financial institutions. State regulators can be particularly effective for issues involving state consumer protection laws, such as deceptive practices or unauthorized fees. Most state banking departments have online complaint forms on their websites.
Filing at the state level doesn’t prevent you from also filing with the CFPB or a federal regulator. In fact, filing with multiple agencies can increase the chance of a meaningful response, since the bank may need to address the same complaint through different regulatory channels.
What Happens After You File
Once a complaint is filed with any regulator, the bank is expected to investigate and respond within the agency’s required timeframe. For CFPB complaints, you’ll receive email updates as your complaint moves through the process and can check its status online at any time.
If the bank’s response doesn’t satisfy you, the CFPB lets you dispute it through your account on their portal. Federal regulators may also investigate patterns of complaints against a bank, which can lead to enforcement actions even if your individual complaint doesn’t produce the outcome you wanted. Your complaint becomes part of the public record and contributes to regulatory oversight of that institution.
For complaints involving unauthorized transactions or electronic fund transfer errors, federal law sets stricter timelines. Banks generally must investigate and resolve these disputes within 10 business days (or 20 business days for new accounts), though they can extend to 45 days if they provisionally credit your account while investigating. Knowing these timelines helps you follow up at the right moments rather than waiting indefinitely.
