Caller: Scammer

Caller said he was from the security dept of a well-known bank - I don't have an account with that bank. Said they've spotted a potential fraud transaction - provided amount & name of person it was supposedly sent to - and asked if I want to retrieve the funds. Told him I don't bank with them, or any of the other banks he started to suggest. He hung up abruptly. Called back on a different line and it was answered by a lady who said she hadn't called anyone.
