Gym contract cancellation

I've been trying to get this sorted since December 2014. 12 December 2014 I sent an e-mail requesting to cancel my gym contract. I received no automated response or any response at all to say it was received or they looking into it. 22 December 2014 then I only received an acknowledgment however right after the acknowledgment I received a query closed email. I then called the call centre to enquire why it is. I then spoke to a young lady called Nthabeleng who informed me that the agent who did that was not supposed however she will send me an e-mail of what is actually required of me. I then waited to respond to them service centre from Nthabeleng however she never sent the e-mail. I then called again after a while and spoke the Shermeela, who provided me with her e-mail address if I want it to be forwarded to their manager. I sent an e-mail from my work e-mail on 2 February 2015 requesting an explanation from management. However the only response I received is another query closure e-mail today again.I've had R300 odd be deducted from my account for the past 3 months for a R149 contract.
