Cancellation of gym Benefit

I joined Vitality and Virgin active at the same time signing a contract of R172 per month. Vitality, without contacting me, cancelled my gym benefit. I have subsequently received a gym bill of R690. When I call Vitality no-one can tell me why they cancelled my gym contract. After numerous calls made I received a call last Thursday 17:25 promising me that it was sorted. A week later and it has not been sorted. I do not want to call their call centre as they do not know what they are doing. They pass me from one to the other. I need an email from Vitality indicating that they are going to reinstate my benefit so Virgin can credit the account on their side. I have no faith that the call centre will be able to provide me with that information due to my many frustrating calls with them already. I have never in all my life come across a more *********** group of people before. I am at my wits end.
