Who called from 5124812913

This number calls me several times a day. They don't leave a message

Don't know who this is or why they called

They called me and said i requested them to call me but i never did

Called me twice anytime I try to call them back they hang up within 2 seconds

Sounds like a call center overseas for debt collection, wanted my SS and banking info. I don't have any debts​. When I told the man, (Raban Jones) so, he became extremely rude, using threats and racial slurs. I tole him I would report him and the number to the FCC and FBI.
