Members filing a complaint involving an account, loan, mortgage, card, disputed transaction, fraud, fee, employee interaction, or service concern should collect account records, dates, transaction details, correspondence, and existing case numbers before escalating.
Begin by calling 210-945-3300 or use secure chat after signing into Online Banking. Explain the concern clearly and provide transaction dates, account type, branch location, and previous communication details. Ask the representative to document the complaint and provide any available case or confirmation number. Do not send sensitive account information through unsecured email.
For disputed card transactions or suspected fraud, use the Online Banking dispute process or call 210-945-3300. Mortgage servicing notices of error or requests for information must be sent to RBFCU, Attn: Mortgage Servicing, P.O. Box 2247, Universal City, TX 78148-2247. Collections issues can be directed to 1-888-556-2965.
If the first contact does not resolve the issue, ask for review by a supervisor or the department responsible for the account. Provide a concise timeline, previous case information, copies of supporting documents, and the specific resolution you are seeking. Keep notes of representative names, dates, and promised follow-up.
For a serious unresolved complaint, mail correspondence to RBFCU, P.O. Box 2097, Universal City, TX 78148-2097.

Mortgage, discrimination, privacy, payment, or consumer-protection disputes may also involve other federal or state regulators.
