A Note for Former Titan Trust Bank Customers

Reporting Fraud or Unauthorized Transactions
If you notice suspicious activity:
1. Call UnionCare immediately on `07007007000` — don't wait.
2. Block your account instantly via USSD by dialing `*826*6#` (from your registered number) or `*826*6*YourMobileNumber#` (from any other phone).

- - If in doubt, visit a physical branch or call `07007007000` directly rather than responding to an inbound message claiming to be from the bank.
