Account not disabled when requested.

I have a concern regarding the virgin active account that I signed up for but was advised by the agent that came to my offices that it can be closed within 5 days and as per him (Solly) I could notify him via whatsapp. I paid a R150 fee which I was happy for them to keep but I instructed him that I won't be interested anymore as I did not have the discovery cover I was planning to get at the same time. The above mentioned person then notified me that he was in an accident and his car was written off and as a result I was waiting for him to confirm. I send a few messages to him to get confirmation but non was received. Virgin Active contacted me a while after that, stating that my account was in arrears. I told them I won't pay as I was not at fault and the lady I spoke to said that I was suppose to call their head office to cancel within that 5 days. That was not what Solly said. I still have the bag he brought me, never used. I still want to use Virgin Active but not with the account that was opened under Solly's supervision. If this account can be canned and then me allowed to start fresh I will gladly do that. I have the discovery plan as well that will allow me to use the vitality. I hope that we can get this matter resolved.
