*****ing from clients !!!

I joined virgin active and was told by consultant that the special for that month was if you paid R1350 joining fee and attended 24 times you would get a refund in the form of an addidas voucher. I called the call centre in December looking for the voucher but was given the run around but no voucher. I spoke to the consultant who sold me the contract and was referred back to the call centre. He also said I did not qualify for the voucher because I missed a payment. ...the payment was taken a few days later so I did not miss a payment. I want my money refunded and contract cancelled.
