Direct T.V. locked into a scam by Direct T.V. Internet

We have had Direct T.V. service for about a year and then moved to a new location.  We took all the previous equiptment, dish, recievers, ect.  They came out and set us up.  No problem.  They then offered "Free" NFL Sunday Ticket.  I declined.  We are not intrested in football.  I fiquered no problem.  A few months go by and I am noticing an increase in my bill.  We don't have a paper bill coming to the house, we have set up auto pay with a credit card.  Big mistake. 

Apperently Direct T.V. began charging for NFL Sunday Ticket.  $32.99 a month.  When I called to inquire, they had already helped themselves to 3 months of this service that I did'nt even know about or care to watch.  I was told that I called 4 days to late.  That the season had already began and that I could not be credited and get this, I am not allowed to cancel!!!! 

I was told I would have another 4 months of this fraudulant charge taken from our credit card that they had on file.  I sent an E-mail to them, spoke to supervisors, requested that they take a look at our viewing history so that they could see that we did not watch NFL Sunday Ticket EVER!!  Remember, when the offered it to us I said NO!!! does'nt matter.  This is staight out fraud and stealing!  can anyone help or advise please.  This is over $230.00 out of our checking account that they just helped themselves to, wont return, and won't let us cancel until the end of the football season.  Unbelievable.
