Security
Tell the fraud team. Money at risk? Call 1-800-555-0126 first, day or night.
Tell us what happened. Never type a card number, a PIN, a code or a password here: the Bank does not need them, and nobody should ask for them.
Just yes or no: never the code itself.
The number or the account that contacted you, what they said, what you did.
The fraud team writes to you here.
