Bad Service - Virgin Active Century City

Last year I contacted Virgin Active Century City requesting to join the gym through my Vitality. I was in contact with a consultant, I cannot recall the guy's name, who asked me to go to the gym with relevant documentation. He explained the costs involved of which I agreed to. Apparently, they had my details on system but when he confirmed my banking details, I advised him that account was no longer in use and proceeded to provide him with my valid ones. He requested I pay him a small fee upfront and the balance will be debited, of which I did.

Two months thereafter I called Virgin Active call center inquiring why there hasn't been any debit orders only to be advised that the banking details they have been debiting are the ones not in use. Frustrated with the news, i request the agent to sort this out ASAP and change my commencement day to the current month in order not to be charged for the arrears. The agent advised me to be in contact with the branch and it has been back and forth ever since.

Yesterday, I get a call from a debt collection company. ***?! I will not pay for services not rendered and for Virgin Active's administration error.

I want Megan McKie, the manager, to sort this out ASAP.
