Incorrect billing and contract

I signed a 3yr contract with Moreleta Club in Feb 2013 which ends in Feb 2016 and I FULLY paid for it. The person who assisted me was Clever Monaise the Sales Manager in Moreleta. I the relocated to Montana branch and paid transfer fees. <br> <br> 3 months ago I discovered that planet fitness opened another 3 yr account on my name and they debit money from my account. I have been calling their call centre for the past 3 months and I haven't got any help. I can't go gym because they deny me entry at the branch. <br> <br> Their collection department was quick to call asking for payments but I haven't got any call regarding the fixing of my issue. Please help.
