Virgin Active has ****** money from my account

I have been trying to cancel my membership since 10 August. I finally received an email from Renee asking me why I wanted to cancel. I responded and my email bounced as that email address is no longer valid. I also tried to 'freeze' my membership to no avail. But guess what? Virgin Active debited my account yesterday with 3 months of membership. Shocking - you have ****** my money and I want it back. Phones are not answered. Does anyone work there and how do I get me money back?
