Virgin Active sort it out

In Jan 2016, I took up a Virgin Active membership, the account was created incorrectly, and therefore billing on the account was incorrect, subsequent to that, the sales consultant dealing with the account resigned. I then converted the account to full vitality and I was meant to be debited with an amount of R170, but R680 was debited off my bank account. I then went to the club informed the sales consultant and he just said it will be sorted out. Today I called head office and I was told a different story, that I must do a medical check only then will my account be changed to vitality. I am so sick of explaining this story, can somebody who cares just sort it out, alternatively please cancel this membership. I don't have the energy, time and resources to be wasting on such incompetence, I just need a place to gym and sweat.
