PLANET FITNESS *****ING FROM MY ACCOUNT

My son and I wanted to join a gym in 2012 through my Vitality membership. Within the first week i requested to cancel as the manner in which the sales consultant handled the contracting was not as it should have been. To date up until yesterday, 3 years later, they are still deducting money from my account - and not all the amounts are the same. I have sent numerous emails to the manager and visited the gym to speak to him and was told they would sort it out. I have put together a schedule of ALL correspondence and have now submitted my story to Carte Blanche as a final resort. I am at my wits end!!!! They have taken thousands from my account for a membership that was cancelled through the proper processes and they don't even have the decency to get back to me when I send emails sometimes. IS THERE ANYONE OUT THERE THAT CAN HELP!!??
