Billing Debacle

I joined GYM Company on a 2 year contract (Maponya Mall) through a sales consultant called Dabulamanzi, who was very helpful and advised I can cancel the contract at anytime of my choosing and after a year I had to relocate due to work commitments. When I went to cancel the contract because GYM Company was fairly new, did not have any facilities outside of Gauteng some revelations which Dabulamanzi did not mention were made, I was told I must find a replacement someone to take over my contract if I wanted out and when I queried this I was referred to Dabulamanzi who in turn was far less friendly and helpful, he told me his on lunch avoided me ever since. Because of the relocation I could not follow up so I decided to let GYM Company deduct monies from my account for the rest of the year without using any of their facilities, but they still kept on deducting even after the 2 year term was over and in turn I had to keep on going to the bank and reversing the debit orders at the cost of R35. As if that was not enough now I have been served with a notice threatening to black list me for a debt of over R2 737.
