Virgin Active owes me a refund! useless staff

on 8th december 2014, i called virgin active to cancel my gym contract ( i know that your calls are recorded!) roslyn confirmed with me telephonically that the contract is cancelled and will end on 20 jan 15 (please get that call!) however, my account was STILL debited. i emailed virgin active on 27 feb and got a reply from Inshaaf who said she will cancel my contract and it will end in march 15. why?? when i cancelled it in december 14 with roslyn already!!! she never got back to me again. my account is STILL being debited in april 15, called and spoke to linda on 1 april. she promised me that i would get a confirmation email by close of business day on 1st april stating that my contract was cancelled in december 2014 already but not actioned by your useless staff and that virgin active will refund my money for feb/march/april . she didnt get back to me either! i expect Virgin Active to get your act together and refund my money for a contract that i cancelled in december 2014!! stop debiting my account and refund the money you owe me you owe me for feb, march and april!! sort it out now!!
