What if I confirmed a code by mistake?

Call your bank immediately, block access, and request a fraud hold.

Can I trust the bank app notification?

Only if you initiated the action. Otherwise treat it as a red flag.

They want to prevent you from calling the real bank.

Is a callback number ever safe?

Only if you find it yourself on the official site or card.
