Shocking service from Virgin Active Accounts Department

I have changed my debit order in May at Virgin Active Tygervalley with all the supporting documentation but to no avail. PSG and Vodacom changed my debit order Immediately without any problems at all and they are companies with millions and millions of clients. It is Sep already and I have begged them weekly, non stop to change my debit order but to no avail. I have begged everyone and complained to everyone but to no avail. Accounts phone me 3 times regarding me not paying but I am the one begging them to change the debit order, they blocked me from entering the Club but I am the one that keeps on begging them to load the debit order as given to them in May. I have never dealt with such incompetency in my life, it is shocking. I stayed at Sir Richard Brandons private game lodge Ulusaba and the service was out of this world, absolutely fantastice but Virgin Active can not change a debit order. Is there anyone in the Virgin Group that will be of assistance to help Virgin Active to change my debit order.
