Overpaying:R700 per month

A year and a bit ago, I was told I could be on your life rewards and only pay R136 per month. Virgin Active did the change, issued a new card, and my fee was to be reduced. 1 and a half years later, I'm still paying the normal fee. I have been promised this will change, they will give me free, as I am over paying, but to date.....nothing. I am going to stop my debit order, because we are entering a 2 year anniversary, disgusting service from Virgin Active
