Wheres my money!!!

At the beginning of last year i was given a free gym membership by discovery at virgin active for being one of the first few thousand members. Discovery informed me that how it works is that you pay virgin active monthly and they transfer the cash to your account every month. My frustration is this. Discovery has not paid me back a cent. For the entire year i have been paying my gym membership and not a cent has been given back to me. I have called countless times, i have spoken to so many people, i even went into the offices in cape town. I have been told that the accounts they paying money into is incorrect, that its virgin active's fault, that i received the money then i didn't receive the money. My problem is supposed to have been dealt with by Mr Kholofelo Shai, but he has tried to pass this issue on to virgin active!!!!- i have received disgusting service. i have sent in my bank statements on numerous occasions, i am so frustrated, i have never in my life received such bad service from any south african company. I am so very disgruntled. Up until now, 5 months later after i first raised this issue i still have not received my money!!! I demand that this be paid to me!
