NFL Sunday Ticket - Online Streaming service

I am looking for a contact in the network group (may be called National Escalation team or NatEsc team internally) within AT&T/DirecTV pertaining to the NFL Sunday Ticket online streaming service. I have been attempting to work through their normal support process for quite some time, they are extremely isolated and handicapped in the support center and I am so frustrated at the impossibility to get any traction through their call center to deal with a network related issue. I have had 4 cases go to their escalation team and they all mysteriously close with no real or valid resolution. I’ve spoken with about 4 or 5 supervisors in their Tulsa call center and they are unable to do much. It has been a nightmare and I am hoping someone has a contact they can get me in touch with.
