Koxo Kickboxing

I was a once a member at the Koxo kickboxing gym. I had canceled my membership in October 2013. January 28th I was charged 79 dollars 24 times!!! When I was a member my rate was only 40 dollars. Once I noticed I immediately called the school and the owner told me he hired a new bookkeeper and when they come back in they will refund me and if the money is not there to contact my bank. Even when I was a member he would run my card before my billing date and one time he charged me my rate TWICE in one month. Now any gym has a point of sale system how is it possible that I could get charged months later a higher rate then I had and have it happen 24 times! If I cancel a membership I expect them to remove my billing information as soon as I quit. A few days later a detective contacted me telling me there was an investigation. Do not go to this gym!!!
