Pure Fitness Scottsdale can't cancel but they can keep charging Scottsdale, Arizona

I was a member of this gym for almost two years, 2 months before it was up I moved to another state. I went in 3 weeks before it was time for me to leave to see what it was that I needed to do to cancel the membership before I left. The manager came and said that if I canceled at that moment then I would have to leave the gym (Im a gym rat I wanted to use the gym for the last three weeks.) Two days before I moved I went back in with the cash to pay out the contract and the girl at the desk said that I needed to talk to Cassie and she was in training the whole week at the gym in Tempe, I said there is no one else to take care of this? NO she said but once your membership is up we can't charge you unless you opt to go month to month. The floor manager/supervisor took my information and said that he would have her to call me. 6 months later I was still being charged. I contacted the gym (It was saved in my phone cause I used the personal training) but apparently when I asked to speak to the manager, I was transferred to Tempe who didn't have access to my information. Then I called back and Nicole the new Cassie was not there I left a message and asked her to call me. NO return phone call. I called again after a few weeks and still no return phone call. So I called my bank and had them to stop the payments, still no call but the emailed me to tell me that the payment didn't come through. AGAIN I CALLED AND NICOLE WAS NOT THERE. (I Doubt Nicole even exist) today I get a call from a collection agency. I am so tired of being ripped off by companies isn't anyone honest anymore.
