Refund

Virgin active consultants came to my work place and i joined the gym. I told them I'm joining for maponya gym not midrand branch. They said it's not a problem they will move it to maponya branch. I signed a contract for R275 monthly installment. I have a copy to prove it. End of November they debited R500, I called to let them (Lwazi from vodaworld)to let them know I was billed incorrectly & he said investigate and getback to me, then Busi (vodaworld) called me and told me i was billed incorrectly and she will fix the problem, that i will be refunded R150 cos i told her to move my Gym membership to alberton New market. So i will now be paying R350 from the 1st January 2016. To my shock again, I was debited R500. After i was promised it won't happen again. So i would like a refund for both months & cancel the contract. I'm fed up with the inconvenience.
