Virgin Active SA continues to deduct monies after cancellation of membership

I cancelled my membership October 2020, and asked for confirmation via email after dealing with the call centre agent.The email confirmed I have cancelled membership. Monies kept been deducted of my account. I have contacted call centre on various occasions in this regard.They eventually confirmed I had cancelled membership in Oct 2020 and I need to forward my bank statement to prove that monies have been deducted for membership off my account. They indicated they would assess and revert back to me.I sent them statement also thinking that they should have their own records to confirm this. After mailing statements I have had no contact. I have contacted call centre via email on many occasions with no joy. I indicated via mail if I do not have a favourable response and my money back I have no other choice than to revert to social media. I posted on Facebook order of events tagging Virgin Active SA. No response or contact by Virgin Active. Yesterday I received an email from Virgin Active's sales department trying to encourage me to rejoin...Am I missing something here?
