Virgin Active & how they rob you!

Approximately 1.5 years ago I joined Virgin Broadacres at a cost of R550 per month for a premium access membership for 2 years. This was more expensive than my Planet Fitness membership but as I had moved to the Broadacres area it was more convenient for me. A few months in I decided to get my myself on a hospital plan and I was told by one of your consultants that I should apply for Multiply and if I came to gym 3 times a week I would actually get a discount off my R550 membership. So I agreed. I work for myself and as times were tough I was forced to cut back on expenses and cancel my Medical Aid within 3 months of starting it. Suddenly I received debit orders going through my account for R850?!! I was furious especially as due to my stressful situation I was not even attending the gym anymore. When I asked someone to explain I was told (unbeknownst to me) that when I advised the gym I was on multiply with momentum I started a "whole new contract"?? And when I advised I was no longer on multiply then a "new contract" commenced at full premium rate! I was absolutely livid as firstly, I did not want to extend my 2 year membership and had someone had the decency to inform me of this I would never have bothered with Multiply!! I was then offered a R742 membership for "off peak access" to the gym? What a cheek after I had just signed up with you a few months before at R550 per month. Eventually the best I could get was R742 for premimum access. I am now still paying R742 per month and have probably used your gym twice this year. I think it is absolutely disgusting that you guys just changed our initial contract without advising me and I believe I should still be paying my original R550. I will never join a Virgin again because there is ALWAYS problems with you guys tying people in to contracts that were not even explained. At no point did someone tell me if I now went of Multiply (which I was now paying extra money for) that suddenly I then have a "NEW MORE EXPENSIVE CONTRACT" for another 24 MONTHS!! I would like someone at Virgin to address this as I am most upset. Over a 2 year period (which i initially signed up for at R550 per month), I am now FORCED to PAY YOU and additional R5808.00 (An extra R242 per month X 24 months)???? Its **************** and it really feels as if Virgin couldnt give a damn.
