Discovery Cancelled/ Vitality Cancelled

I joined Virgin in December 2014, was with Discovery at the time and was paying R 86.00 per month as per the contract I signed. In February 2015, I was retrenched. In April I noticed an amount of R 430 deducted by Virgin off my account. When I called I to ask why I was advised this was because Discovery/Vitality advised them my membership to Discovery was cancelled &I now had to pay the full amount pm as per my contract. I asked for a copy of my contract where this is stated & where I signed &accepted this as no one had mentioned this to me when I joined & no one had given me a copy of my contract. I was told it was mailed to me at the time. I got no mail. When I asked for a copy of said mail, it never came. I was sent a copy of my contract & nowhere does it state that in the event my Discovery/Vitality is cancelled I would then be charged R 430 a month. I got no help and was told they can do as they wish.I mailed the manager of the club Robin Derckson, he called me to say it is in the contract, it isn't. I asked him to show me where, he couldn't. He said he would come back to me. He didn't. He has now left the gym and no one is answering me or coming back to me to resolve this.
