Zone Fitness completely unproffessional

I have had a zone fitness membership for just over a year now. The contract agreed on ended at the end of January 2015. After it had ended the gym continued to debit my account as if the membership just continued past the end of the contract maturity. I then called zone fitness, where I spoke to the manager at the Kloof street branch. He informed me that it's standard practice to continue the membership past the maturity of the contract on a monthly basis. (Contract can thus be cancelled at anytime)<br> <br> I said at that point, that i don't want this account any longer, and would like it to be cancelled. He then responded and stated that if I want to cancel it, I need to send an email to him cancelling this contract. I did this on the 3rd of March 2015. At the beginning of April 2015 my account was debited again. i have tried to contact Marcus on two occasions, and he has not returned my calls. I forwarded the same email to him again, and again, no response. This is completely unprofessional, and I don't understand how this can be allowed by an organization/company.
