Virgin active won't assist me in cancelling my membership

Cancelling my membership has been nothing short of trying to pull teeth from a pitfall.I cancelled my membership in July 21/07/21 got an automated response but the debits are continuing to go through.I got a response on the 9 October from one of there agents who had all the information but still gave me a rhetoric email feedback.The sad part is I can't even reverse the debit in fear of damaging my credit report
