Delray Fitness Fails to cancel memberships when requested continues to charge your account delray beach, Florida

I joined Delray Fitness in 2010 which included 1 yr contract after which I could cancel with 30 days notice.  On October 5, 2012 I requested my member ship be canceled and completed the form they had me to and submitted to employee Robbie on Sunday. I was told it would be 30 days to be effective which meant I would be charged for October 25th membership charge which I acknowledged.  November the membership charge was taken out again.  I contacted the gym on two occassions and todate have not received a call back from anyone despite being assured someone from "bookkeeping" would be calling me.  I resorted to disputing the charge through my bank and after an investigation the bank reversed the charge stating my claim had been "confirmed".  On January 10th I received a call from a collection agency on behalf of Delray Fitness stating that I needed to contact them on a serious matter.  I called and was told I was in violation for not paying my membership dues.  I explained to the representative my entire story.  She placed me on hold and called Delray Fitness.  Robbie actually answered the phone and confirmed my story but I was told to produce a copy of the form and they would review my request.  I advised them that I was reporting the gym to the Dept of Agriculture who governs gyms in Florida and filing a complaint to the newly formed Consumer Financial Protection Bureau that oversees consumer financial matters including collection agencies.
