All contract details to me were False!

Enrolled Thorugh a Salesman Zain Harij. He told me membership will be R89 a month and thur promotion "Gym winter for free". I agreed signed for Rustenburg Town and paid my initiation fee to him. He phoned me the next day and says no my fee will be R179pm. I agreed and left it because he dont me if I want to cancel i must phone head office myself, and i dont have the time for that. Next bad thing is end of the same month i was charged ! So the gym winter for free is A LIE ! It gets worse! Today i go to the gym to fetch my tag, when there they tell me i have not been enrolled to this gym! There must be a mistake, i must go to the other gym to fix the mistake! This is ridiculous
