Virgin active ****

Virgin Active Glen Marais is a ****. I was interested in signing for membership with them in July. A lady who works there by the name of Noxolo walked me through the process of joining and getting a five day free trial before officially becoming a member. She even went to the lengths of coming to my home. She clearly stated upon signing the form, I am eligible to use the gym for 5 days to see whether I'd like to become part of their family. I also wanted my baby cousin to join, Noxolo and I have communicated this. On the 5th day, it was a Saturday morning when I went to the gym with my cousin as per our agreement with Noxolo. Anyway she also came with me during the week in this period of what they call the Free trial. So on Saturday morning when we were at the reception, another employee of the gym told us off. Even after I explained that we're still in the 5 day free trial and she can call Noxolo because she was off duty. She treated us very badly and didn't have a care to understand before telling us we're not allowed to go in. Eventually we left, and while we were outside I took it upon myself to call Noxolo (the lady I signed up with) and told her that her colleagues are rude. They have treated us badly so I am not interested in joining anymore she can cancel our agreement. She was not at work like I've mentioned but she assured that she'll take care of it as soon as she's there. I left thinking that I'm done with Virgin active, they will never see me. Come month end September I see they debited my account. I obviously reversed it. Now I'm getting phone calls asking what happened. I've explained to atleast 3 consultants at the head office but they also debited my account on Month end October. I reversed that too. When I call this Noxolo lady she tells me that she told me to cancel by writing a letter 20 days before debit day. She is lying. I could've done that I mean is she trying to insult my intelligence? Yesterday I received a phone call from head office telling me about a cancellation fee of R100 and something as well as a penalty of R3000. I mean I literally used that gym for 3 days and now they are telling me about an amount over R3000? I am not willing to pay such an amount because I can't to afford to. Please help!
