COLUMBIA HOUSE DVD CLUB

I HAVE EMAIL,WRITTEN AND CALLED COLUMBIA HOUSE DVD CLUB TO CANCEL MY MEMBERSHIP AND STOP WITHDRAWALING MONEY FROM MY CHECKING ACCOUNT SINCE DECEMBER 2008. I SPOKE WITH A GUY NAME EBAM AND MEAGAN ID#2532 AND SAID THEY DO NOT OFFER CANCELLATION NUMBER CONFIRMATION, BUT THEY WOULD SEND ME A LETTER. EACH TIME I HAVE NEVER RECEIVED A LETTER, BUT THEY CONTINUOUSLY WITHDRAW MONEY. THE COMPANY IS A SCAM.
