<prompt> Human: Had credit card with Synchrony Bank, cancelled it with a balance on it in my favor, bank cut my refund check July 16th. Well, the check never arrived so I requested a stop pay reissue the first week of August. In mid-August I was sent a check image with my signature on the back, only the signature looks nothing like mine. I called the bank the same day I got the check image and was told to ignore the check image and wait four more business days for my refund check to arrive. On August 29th I finally called and, after speaking with a supervisor to find out what was going on, Synchrony bank informed me the check had been endorsed and cashed in late July. I let them know I never received the check and the signature on it was forged, so the supervisor tells me Synchrony Bank will launch an internal fraud investigation which can take up to 15 business days. People I talk to at this bank dont seem like they give a crap or have a clue and several times have just told me b.s. to get me off the phone. For example, nobody even told me the check had been cashed until August 29th, despite having talked to bank reps three times since the check was cashed. I dont think theyre going to open a fraud investigation, get back to me, or anything, I honestly expect to get dicked along indefinitely until I give up.The check image I received in mid-August doesnt have any kind of bank imprinting on it like casheddeposited check images typically do, and it doesnt show having been endorsed over to a second party, someone just flat out signed it with my name. This also makes me wonder how it was possible to cash this check, does this imply someone forged my name on a bank account?What can I do about this? I never received the check, if they even mailed it to the right address. No clue who signed it but it wasnt me. Never had this happen to me before and am totally lost.Also, if the bank doesnt make this right what recourse is there?  <response>: Banks actually do take this stuff seriously, its just so routine as to be a non-event for them. You arent going to get the FBI to show up guns drawn and the president of the bank calling you to let you know hes personally on the case. They will find the cashed check and compare the signature to yours and likely make it right. Its standard procedure stuff. Best thing you for you to do is be patient but diligent, if the 15 days comes and goes with no response call back and politely escalate.
