ABC Financial Services EOS Fitness Told I could cancel my gym membership when I moved out of state, now turned to collections Sherwood Arkansas

I was only going to be in Las Vegas for approx 90 days so I joined a gym that assured me I would be able to easily cancel my membership when I was called back to work. 

I informed the gym that I would be leaving at the end of March 2017 and was informed that I would need to call ABC Financial and tell them, which I did.  In July of this year ABC Financial called me and said that I had to contact a different department to cancel the personal training portion, even though I no longer had a membership, and this had to be done in writing.  I did this and was then called and told that I had to provide proof that I had moved over 25 miles from the gym.  My utility bill's for my rental were in my husband's name so they would not accept these.  I sent a copy of my house rental agreement and this was also deemed insufficient. 

I then sent them a letter from my employer and did not hear from them again until today when I was contacted by a collection agency and told I owed over $7000.00 to ABC Financial.  I contacted ABC directly after that but the agent said he couldn't give me any info about my account since it had been turned to collections but that he could email a supervisor and ask them to contact me.  I have spent more time disputing these gym charges than I did at the actual gym.
