We cancelled our Netflix account in December 2011.  I noticed several months later that they were still billing my credit card, so my son called again to make sure it was cancelled.  They said the account was closed.  I noticed in July that I was still being billed.  I called Netflix and they again said our account was closed.  When I told them they were still billing us, they said there was another e-mail address with our credit card name attached to that account. 

What I don't understand is they only billed me for one account while we used Netflilx, and then they supposedly cancelled that account, but then continued billing me.  Now they say it is a fraudulent matter and I have to contact my bank.  They will not credit my card, even though we have not used their services.
