Zone Fitness Westgate Mall - please sort out your accounts and admin department

I am livid with Zone Fitness. I joined months ago via the Westgate Mall branch and then added my son and a family member to my account. Every month, without fail the debit order of R620 goes off my account and every time my son tries to use it, there is an issue. He is told that the account is overdue and blocked. I have emailed, I have phoned and still THE SAME PROBLEM and every time a different excuse as to why it showing overdue. My last complaint was on the 30th April when I received an UGLY SMS telling me to contact them urgently and to pay immediately. I was assisted by Samantha Noble and she emailed me confirming all was in order and there should be no more problems. She advised that someone in the admin department clearly did not doe their work correctly and that is why it is showing in arrears? As the customer I am not interested in which department caused the error. I just want it sorted!

Today my son went back to gym and was blocked! He let me know and I called the gym immediately. I asked to speak to Sue who is in charge of the accounts/finance department. I was transferred to her and then told she is not available - she is speaking to my son and sorting it out. I insisted speaking with her and then told she is not available????????? REALLY? Was she just not speaking to my son??? NO ONE TAKES RESPONSIBILTY and it is really really bad customer service. I want this contract cancelled - the service is unacceptable and I seriously want this contract with my 2 add on's cancelled. No excuses for poor customer service - I am over it now.
