Business ProfileforExtreme Family Fitness

I am an over the road truck driver and was out of the state when I tried to cancel my membership. I was told my wife can come in to the gym on my behalf and sign the cancellation notice. She went to the gym back in September to sign the notice was told that I owe no money and everything was gonna be fine. It was all done on the computer so she wasn’t given a copy. The gym told me yesterday that they accepted the termination back in September but still need to pay $15 for September, so I payed the 15 dollars hoping this would finalize the termination of the contract . The lady at the front desk told me that management would get in contact with me through email with the final cancellation copy, but have heard no nothing back from management. I have received collection calls and also received an email yesterday from a collection agency saying that I owe them over $100 for extreme fitness monthly bills. I explained all this to the lady at the front desk yesterday and also to someone on the phone at the front desk yesterday evening. I feel extreme family fitness is railroading me with this cancellation of their membership so they can keep the contract open and keep billing me. I need help in resolving this issue.
