<prompt> Human: My bank shows a wire transfer to my account for 20. I have no idea who sent me this money, and although I do have the reference number for it, I dont know howif I can do anything with it to figure out who sent this to me. This may sound paranoid, but should I be worried at all? Clearly someone knows my account and routing numbers, could someone do something malicious with that information or with this wire transfer?Additionally, my bank charged me a 15 fee for the wire transfer. I guess I came out positive in this case, but it seems a bit backwards that Id be charged. If this random wire transfer was 1 for instance, I wouldve lost 14 for no reason. Any advice would be appreciated. My bank is BBT if that makes a difference.  <response>: Contact your bank-let them know its an unexpected wire.
