Virgin active is STILL *****ING FROM ME !!!!!!!!!!!!!

I have 'cancelled' my account 3 times. I have had multiple phone calls with Virgin Active cancelling my account which they confirm has been completed and yet it's still coming off my account every month. They overcharged me on my original contract and have still not fixed it!!! Absolute *******!!!!! There is no customer support and absolutely USELESS people working for this company.
