Not given 75% vitality Virgin Active discount as promised

I am truly disappointed with Discovery Vitality & Virgin Active. For the last 2 years I've been paying the 75% discounted rate. Due to extensive travelling for work I was unable to keep the rolling yearly number of 36. My rate for Virgin Active on the 50% discount was R275 and before that it was always R137.50. In July I was then told that there was some issue with my account and my current 50% rate is actually R412.50. This was not what I signed up for. I was always told that I will pay around R140 for the gym membership on 75% discount and R280 for 50% discount. This is what I agreed to. I tried querying these amounts and was told a whole bunch of useless stories about how someone put me on the wrong membership. I was then advised by both Discovery and Virgin Active consultants to make sure I got 36 rolling times swiped on my gym membership for August so that come beginning September I will pay a 75% rate of R206.25 for my gym membership. This was not what happened. I ended up paying R412.50 yet again and when I tried querying it I was now given a different story about how I will only pay 75% in October. This is utter nonsense seeing as I was told by 2 consultants that it would reflect in September. Please just give me back my money and cancel my vitality and gym membership. I hate being **** to and cheated.
