My wife received a phone call this morning telling her "the bank" (no brand of bank) had overcharged her $4288.00 on purchases. She was urged to ring a phone number that the kind person provided so arrangements could be made to return the money to her. She didn't ring and ten minutes later another call saying that they were waiting for her phone call, again she didn't bite and another phone call. When the third phone call was received she looked at the caller ID and seeing it was from OS let it go through to message bank. No message and no further phone calls so far. I haven't heard of this scam before and have always warned against providing any details on the phone if asked so I guess they wasted a bit of time which is the only satisfaction I get out of the whole thing.
