Um, DTV's customer service is right here in the USA. I don't know if it's staffed with Navajos, Kiowas, Creeks, or Chickasaws or not.
While I've had one bad experience with them, it was over an arcane matter of Motorhome Exemptions for Distant Networks which was partially my fault for improperly explaining, the vast majority of my DTV experience has been quite positive. Plus, for most programming changes, you can simply make them online and by the time you log off, the changes are in effect in your service.

OT perhaps, but try calling AT&T customer "service".
