Virgen Active Potchefstroom is pefetic

I went to Virgin Active Potchefstroom to hear about costs to join the gym. They had a student special, and said I should sign up now to get it but I do have a 5 working day period to cancel it. So I signed up, I talked to my parents and they said that I should rather cancel it so we can first see about our money situations, so I asked the guy who helped me sign up to cancel it. He said he would do it. A few days later R315 was drawn from my account by them, I phoned and the guy said that I was after the 5 days but I wasn't so a few days later he said the contract was cancelled and they will pay my money back. A month went past but I still didn't receive my money back and then today they draw another R315 from my account. It takes them 10 minutes to get you signed up but now it's now more than a two months and my account is still not cancel and they keep on taking my money, I'm going to have to close my bank account.
