Zone fitness contract cancellation

I have been trying to cancel my account for the past 5 months. I was retrenched and could no longer go to that gym or pay the premium. I acknowledge that I need to pay the cancellation fee and have asked to arrange a payment plan where I can pay my cancellation in installments. I have sent a number of emails but have gotten no response. I am still being debited even after I have repeatedly asked to terminate my contract. The worst part is I had requested a 12 month contract but the recruiter wrote 24 months on the contract. I have called and sent countless emails but haven't gotten any help. I called the head office and was told that they cannot help me. It's pretty clear that this company does not care about their clients and are only looking to ***** money from us. If you can harass me with ten million sms's, surely you can contact me and resolve this. I am very displeased with this company and wouldn't recommend it to anyone. Their customer service is atrocious!!! Please advise on a plausible way forward.
