Scam/Fraud
15 Oct 2025

My colleague was called about attempted fraud in our bank account and asked to call this number, NatWest fraud line. This is not a NatWest number so clearly trying to scam our details from us.

This number was tagged as potential fraud so i didn't answer. Rang me twice in quick succession, however no message left which is odd behaviour if from a legitimate caller.
