Virgin Active horrific service to clients

Virgin Active constantly debits my account wrongly. They then hold me liable for payments, I have made numerous calls to the call centres and my membership is blocked even though I have honoured my commitments. I have called the call centre manager and the call centre on numerous occasions and they ignore me. I cannot go to the gym as they unblock my membership constantly the call centre manager Izrah Rossouw and she ignores me. Last month I was debited wrongly and I had to call again.
