ABC Financial Worst membership I've ever had Internet

 I read a report giled against ABC Financial and they replied stating they couldn't find the users info.  Research any gym that uses ABC financial and read the reviews.  They all explain the nightmare cancellation policy.  I've been told to join a website to cancel my gym membership, after providing contract number they require a key card number.  my contract has been expired for 7 months, but no one can cancel it.  Thats $420 they have billed me.  I changed my bak card twice and my bank doesn't understand how this crooked company processes payments through the new bank cards they give me.   There are concerns of identity theft, since I have never provided the necessary info to ABCFinancial to do this.  I wish I would have bought lifelock credit protection so they could go after these guys.  Next step is change banks, if that doesn't work I will change my name and ssn# hopefully that will stop them
