Random Stoppage of Virgin Active Contract

I joined virgin active on a promotional deal where I'd Pay R370 monthly for a 2 year contract, I joined and Signed my contract at the Tygervalley gym. After three months of using the gym today when I went as usual they informed me that i cannot gym at the Tygervalley gym, I can only use the gym in Mitchells Plain. I was obviously confused and stated that I have been using the gym for three months now and wanted to know what was happening. I spoke to the consultant with whom I signed up and he stated that my contract has STOPPED and I can only gym at Mitchells Plain or pay for a new membership (WHICH IS DOUBLE THE PRICE) or I'd have to cancel, which would also cost about R5000. I tried to contact head office but to no avail and as you can imagine I am Fuming

Can anyone help me on this
