very unsatisfied with virgin active south africa

I am very very ANGRY at virgin active, I have freezed my account for 4 months but they deduct the full amount in the middle of may and again half of the amount at the end of may. now they saying i have freezed my account at the end of April while the debit order went through. i called last week and the consultant confirmed that i am supposed to be refunded for the debit that went off month end of may. and said i will get a refund in two to four days. after 6 days i noticed that i still did not get my money then i dispute the debit that was made. then i now receive an sms saying i am owing them how so?? i am so irritated and i even regret why i joined this club in the first place. and the real reason for me to freze the account it was because i was very unsatisfied about their service. i so cant wait for the contract to come to an end so that i will leave and get a gym that will have customers best interest at heart.
