Disgusted at the service

On the 28th of August I called the call centre as I wanted to be able to visit the carlswald gym. I visited the gym and called back on the weekend to let them know I no longer required access to the gym I preferred to stay at Boulders. They do not work on weekends so i got through to them today. The consultant Lexi said she changed my gym back to Boulders however they could not credit my account. The charged me R250 in advance plus a R50 activation fee. Also she will still charge me R200 for cancelling. I told her that it is not even 7 days and i paid in advance so i'm entitled to my credit to which she said I knew the terms and conditions. This is terrible customer service and *******.
