How to File and Submit an East West Bank Customer Complaint Form

To file an East West Bank customer complaint, call 888-895-5650, use the “Message Us” form on the bank’s website, email talk2us@eastwestbank.com, or mail a written complaint to 135 N. Los Robles Ave., 7th Floor, Pasadena, CA 91101.¹ The bank does not publish a standalone complaint form; the right channel depends on what went wrong, and federal deadlines apply to both you and the bank the moment you report it.

How to Reach the Bank

Phone is fastest. The customer service line at 888-895-5650 runs Monday through Friday from 6:00 a.m. to 7:00 p.m. PT and Saturday from 9:00 a.m. to 5:00 p.m. PT, and an oral notice is legally valid for electronic fund transfer errors. For a lost or stolen debit or ATM card, use the dedicated line at 800-236-2442.¹

The website’s “Message Us” form has one important limit: the bank instructs you not to include account numbers, PINs, or balance information in it.¹ Use it for general questions or an initial ping. For anything that requires specific transaction details, call or write.

A mailed letter to the Pasadena headquarters creates a dated paper trail, which matters if you later need to prove when you reported the problem. For larger dollar amounts, send it certified with return receipt.

What to Put in Your Complaint

Include your full name, account number, and enough detail for the bank to identify the transaction or service in question. For an electronic fund transfer error, federal rules require your notice to state the type of error, the date it occurred, and the dollar amount involved, to the extent you can provide them.² If you already spoke with a bank employee, note that person’s name and the date of the call.

Credit card billing disputes are different. Your notice must be in writing, must go to the billing inquiry address printed on your statement, and must identify your name, account number, the billing error you believe occurred, and the date and amount of the charge.³ Attach copies of receipts, statements, or screenshots. A phone call alone does not satisfy the credit card requirement.

The 60-Day Deadline

You have 60 days. For electronic fund transfer disputes, including unauthorized debit card charges, ATM errors, and incorrect direct deposits, you must notify the bank within 60 days after it sends the statement showing the error.⁴ Miss the window and the bank has no obligation to investigate.

For credit card billing errors, the deadline is also 60 days, measured from the date the creditor sends the first periodic statement reflecting the disputed charge.³ The clock runs whether or not you opened the statement.

What the Bank Has to Do Next

Electronic Fund Transfer Errors

Once the bank receives your notice, it has 10 business days to investigate and decide whether an error occurred, and must report its findings in writing within three business days after finishing.²

If it needs more time, it can extend the investigation to 45 days, but only if it provisionally credits your account for the disputed amount within the initial 10-day period and gives you full use of those funds. The bank must notify you within two business days of issuing that credit.⁵

The 45-day window stretches to 90 days in three situations: the transfer was not initiated within the United States, it resulted from a point-of-sale debit card transaction, or it occurred within 30 days of the first deposit to a new account.⁵

One catch on provisional credit: if you reported the error orally and the bank asked for written confirmation, you have 10 business days to send it. If you don’t, the bank can withhold the temporary credit, though it still has to investigate.⁵ Follow up your call with a letter or email to close that gap.

Credit Card Billing Errors

Under Regulation Z, the bank must send you written acknowledgment within 30 days of receiving your notice, unless it resolves the dispute in that time. It then has two complete billing cycles, and no more than 90 days from receiving your notice, to investigate and resolve the issue.³ While it investigates, it cannot try to collect the disputed amount or report it as delinquent to credit bureaus.

Where to Escalate

If the bank’s internal process doesn’t resolve your complaint, three agencies can push back on it. East West Bank is a California state-chartered bank and a member of the Federal Reserve System.

The Consumer Financial Protection Bureau takes complaints about any bank. File online at consumerfinance.gov/complaint, describe the problem in your own words, and attach up to 50 pages of supporting documents. The CFPB forwards the complaint directly to East West Bank, which generally responds within 15 calendar days and has up to 60 calendar days for a final response.⁶ The CFPB is authorized by federal law to run this complaint program and monitor company responses.⁷ You can track your complaint through the online portal and provide feedback on the bank’s response within 60 days.⁸

The FDIC takes complaints online at ask.fdic.gov or by mail to the Consumer Response Unit, 1100 Walnut Street, Box #11, Kansas City, MO 64106. If a different federal agency actually regulates your bank, the FDIC forwards the complaint.⁹

The California Department of Financial Protection and Innovation regulates state-chartered banks like East West at the state level. File online at dfpi.ca.gov or mail a completed complaint form to the Department of Financial Protection and Innovation, Attn: Consumer Services, 651 Bannon Street, Suite 300, Sacramento, CA 95811. Its assistance line is 1-866-275-2677.¹⁰

Your Right to Sue

If the bank violates the Electronic Fund Transfer Act by failing to investigate, withholding a required provisional credit, or blowing past the deadlines, you can sue for actual damages plus statutory damages of $100 to $1,000 per individual action. Statutory damages don’t require you to prove a specific loss; the violation itself triggers them.¹¹

Small claims court is a practical option for individual banking disputes. Filing fees generally run $25 to $300 depending on the state and the amount claimed, and jurisdictional limits fall between $5,000 and $20,000 in most states. You don’t need a lawyer. East West Bank’s Deposit Account Agreement, as of its June 2024 version, does not include a mandatory arbitration clause, so you are not required to waive your right to go to court.¹² Check the current version of the agreement before filing, since banks can update their terms.
