Virgin Active Victory Park debited my account monthly after I canceled my membership.

I was a member at Virgin Active Victory Park until the monthly subscription price had gone up. I then canceled my subscription due to the fact that I couldn't afford it any longer. When this process was completed I recived a blue subscription cancellation receipt. About 10 months down the line I see that Virgin had been debiting my account every month even after I had canceled my subscription. I go back to Virgin Victory Park and ask for a refund of the amount that was wrongfully debited from my account. I was then told that this would not be happening due to the fact that I was still on their system. I explained to them that I had canceled my subscription 10 months before and I even recived a blue cancellation receipt. They refused to refund the amount that they stole from me due to their inability to correctly process a subscription cancellation.
