Cablevision KEEPS CHARGING MY CREDIT CARD ATER I RETUNRED ALL OF THERE EQUIPMENT Bethpage, New York

I HAVE CALLED EVERY MONTH SINCE JUNE THEY KEEP CHARGING MY DISCOVER CARD FOR SERVICES I HAVE NOT RECIEVED I RETURNED ALL OF THER EQUIPMENT IN JUNE. AND THEY KEEP CHARGING ME I CALLED TODAY BECAUSE THEY DID IT AGAIN AND WANTED TO SPEAK TO A SUPERIVISON AND THEY WOULD NOT LET ME.  EVERY MONTH I CALL DISCOVER AND THEY PUT IN A DISPUT AND CABLEVISION REFUSES TO ANSWER THERE LETTER THAT THEY SEND.  I HAVE RECIEVE SOME OF A CREDIT BACK FROM CABLEVISION BUT NOT THE LAST TWO CHARGES AUGUST AND SEPTEMBER .  I WANT MY MONEY BACK AND WANT THIS TO STOP THIS AT ONCE.  THIS IS A BIG WASTE OF MY TIME EVERY MONTH AND I FIND IT REALLY TERRIBLE THAT THEY HAVE CAUSED ME  ALL OF THIS GRIEF AND WOULD NOT LET ME TALK TO A SUPERVISOR.
