Moove gym a BIG ****

I went into the gym on the 2nd of August to renew my gym membership. Alexa informed me that Viva gym was taken over by Moove. She said that that national membership has increased from R489 to R600 and I agreed to sign up. I paid R300 for 1st month gym fee as she said it was discounted. A few minutes after I drove off, she called me and said she forgot to tell me that I would have to pay an extra R30 for maintenence levy every month. I immediately told her that I felt ******* and I didn't want to continue with the contract. They have refused to refund me and to confirm cancelation of the contract. I have been calling every day to follow up and their manager is not available for feedback and I was told that if head office has not done anything there is nothing they can do. I backed out within minutes of hearing about their additional charges.
