Vonage Cancel! Cancel!! Cancel!!! Internet

Oct 09, 2010, I contacted vonage regarding service.  I was told my phone number could be transferred to vonage, so I gave my credit card information and set up an account.  The same day, I was told my number could not be transferred to a vonage account so I asked them not to open an account for me.  I was told it would take a few days, but the account would be closed.  Dec 09, 2010 I saw they were still charging my account, so I again cancelled the account and asked for a refund of the charges to my account.  They said they would cancel the account but could not refund the charges.  Jan 11, 2011 I contacted them again because my account was charged on Jan 09, 2011.  I again cancelled this account and asked for a refund, they cancelled my account but refused to issue a refund.  I cancelled the credit card they were using to charge my account to ensure they could not charge my account again.  On Feb 13, 2011, they managed to charge my account again.  Today I contacted my bank to report these fraud charges, and vonage to find out why they charged my account.  I was informed my account was still active, so again, I went through the cancellation process with vonage.  Lets see how many times it takes to cancel.
