Who called from 2147750864

This number appeared on my home phone that is unknown to me and believe it is unwanted.

Claims to be from US bank. Called back twice and got 2 different stories.

First time I had an old account that they wanted to credit with $500 dollars if I updated my personal info. I do not have an account here and have never even heard of them before this phone call.
Second time I called them they wanted my personal info so they could send me my new debit card. This has identity theft and info gathering for bill collectors and mailing list written all over it.

calling me at different times of the day and I do not know them..

The caller left no message. I am not sure who they are. I will not try to contact them.

not sure who it is and don't care for them calling me.. i'm omn the do not call registry list.
