Double Debited and misleading information

We joined the gym two months ago on the R199 for the first 3 months. To start with, the sales representative told us we would receive a free bag if we join. After we joined he told us that we cannot get the bag, because you must take a card with you every time you go to the gym and get it signed by the gym staff for a number of times before you can get the bag. This was not explained to us before the time. Now this month I got triple debited, R264 and R199 x 2 debit orders from my account. After phoning them the lady was rude and told us that the extra R199 was a yearly fee, how can you charge a yearly fee, we just joined the gym?? The R264 she explained was an issue and we have to wait 14 working days before we get our money back? After arguing with her about the money, I told her we are going to cancel the gym contracts. She told me that I can, but then I have to pay the contract in full. How do you breach the contract and do unauthorized debits from my account and except me to pay the reminder of the contract if I wish to cancel? Sorry Planet Fitness you have lost two members and I will not recommend you to anyone else.
