<prompt> Human: Im not sure if Credit Score problems belong here in rpersonalfinance, but I dont know where else to turn!So I dated a girl and we broke up about a year ago. She had signed me up for a gym membership about a week before we split. I never signed any papers, or gave them any of my personal information.About 2 months ago I started getting automated calls from the gyms payment company, saying it had important details about my account. I simply disregarded these, figuring they would eventually stop calling.Well I just received a call from a debt collecting agency, saying I owed them 75 for the outstanding account balance. I refused to pay it on general principal, but it is going to hit my credit score immediately. I called the gym immediately after and the manager was busy, so Im going to call back tomorrow.The debt collector repeatedly told me about all of these things policys on cancelation and outstanding balance procedures that I had agreed too. Again, I never signed any papers or made any contact with the gym whatsoever, I didnt even use the facilitys one time. It was all originally on my exs credit card, and she cancelled it as soon as we broke up for obvious reasons. All she ever did was put my name on the account as well.What do I do!? I think the gym manager should be able to help, or should I try to contact the credit bureau and dispute these allegations? I can try getting a lawyer, but lawyers cost money and this shit wouldnt be worth it.On a side not I read a post recently that said you can make 500 each time you receive an automated collections call. If I do get a lawyer could I make money on this? I live in Arizona, and they called me maybe 20 times.I really appreciate any help, the rpersonalfinance community has been great to every question Ive ever seen asked.  <response>: What happened to you is called identity theft. You need to get a police report and send the collection agency a copy. Then if it shows up on your credit report you dispute it with a copy of your police report.
