transfer of memebership

I am writing because I believe I have gone through all avenues in VIRGIN ACTIVE I signed gym contract with Virgin Active under a promotion of R100 in June 2015.I explained this to the Sales person that I am not planning to pay a membership of R600 a month so he should assist me with converting my membership to either Vitality or Multiply. I ended up activating Momentum and informed the Sales Consultant ,I will be coming to sign a new contract I went there the system was offline I DIDNT GET HELPED.I called to check the following day they were still offline VIRGIN ACTIVE DEDUCTED R600 01.07.15. I visited the branch twice&they were still offline, but they allowed me to swipe for R130&handed me a new card&said they will process everything later when they online&I was going to get my refund in 7 days nothing happened. I went to get help at Cresta&I was informed nothing was activated I owed R130&I told them that were not the true R600 was deducted again 01.08.15called TANDAI said they will investigate they investigated& found proof that I paid and they were going to refund me. nothing has happened. I called the head office 2 weeks ago and no results.I now don't know what to do.
