Deductions on a cancelled contract

In may 2015 my contact with Virgin was supposed to be cancelled as I signed a 1 year contract therefore I hadn't made a payment I then received a call from the head office saying they require payment for that month and that the gentleman I was speaking to would cancel my membership. They debited my account for two payments of 410. This is now a new month and I am still being debited I am told there is an automatic renewal of contract if you don't cancel the contract. I have done this with head office and where in the contract does it state that there is such renewal?? In the past they deducted money from my account for a personal trainer which I have never received training from now this?? Pathetic service from your Pinetown staff
