bad service

I dealt with a consultant whom signed me up and said that once my vitality is active that I would pay R200 gym fees. (This is at the vodaworld Virgin active in Midrand) I signed the contract then came in again to activate my vitality- for two months I have been debited vitality fees plus R800 gym fees. When I went in to query this and ask for a refund the manager said She cannot assist me as the sales consultant is not in and she cannot say when he will be in and I will need to pay another R350 to change my contract from normal to vitality

My account is now in excess due to these charges and they still expect me to pay more to change my contract while my account is in excess as the manager said that's all she can do.
