Poor service - change of banking details

I changed my bank account, thus needed to change debit orders on both myself and my partners gym accounts. first I call the oakdene centre which the advisor there asked me for my details which I provided, was called back to advise that both membership account details were changed, confident in the service received never thought anything until the point I realised that the old account was debited again. I call the gym again and advised that we cannot change it from there I need to send an email to headoffice or change it on the online portal, which I opted to change online which informed me this was changed, only to receive an email to advise me that the viva debit order bounced back, I called the centre again to confirm they said they have no access to view. I sent an email to headoffice which I received a mail back next business day, to my knowledge the account were changed however to the incorrect account. I gave headoffice the correct account details and advised them to change both myself and my partners account details as the debit goes through one account, advised that both would be changed. finally some closure to the frustration only to find that only one membership was changed, my partners account is now in arrears to this incompetency and we are due to pay R 550.00+- . I find this very inconvenient and pathetic.

I have since cancelled my own membership with Viva and have moved to another gym and wish to cancel my partners too. I do believe I will not be debited for this months gym subscription as we shall not be going back.
