NFL Sunday Ticket Titans vs Browns

Yesterday, I was unable to watch the Titans vs Browns via the NFL Sunday ticket.  I got a message saying that the game was blacked out for me.  The game was not being televised on one of my local channels.  I live more than 150 miles from Cleveland (where the game was played) and the game was sold out.  Why would I have a black out?  I spent more than an hour on the phone with customer service and no one could give me a reason.  As silly as this may seem, the only reason that I have directv is to watch the Browns on the Sunday ticket. This is my third year with directv and I have not had an issue the previous two years.  I really need to talk to someone who can tell me why the game was blacked out for me.  The customer service reps that I talked to yesterday did not seem interested in finding out why I had the black out.  One rep even said that there was no one in their organization who could tell me why I had the black out.  Does anyone have a good phone number or email address that I can use to talk to someone about this.  My fear is that I will be blacked out for future games thus, rendering my directv useless.
