Well it went from "a friend of mine" to "I'm not trying to scam".
Who says you can't borrow yourself out of debt?
It sounds like they already called Dish and have service scheduled under the new name. With that said...
I wonder what type of package, promotion, etc... was arranged. If the new service includes some sort of commitment, then the roommate will not be able to cancel it without paying penalties and/or having a few points taken off his/her credit score.
Also, starting and stopping service usually involves a few dollars, and then there may be activation fees for new accounts.
If not able to pay, I think maybe they should of tried:
...(a) Ask Dish if they can pay the monthly amount plus a few dollars until caught up.
...(b) Until they can pay off what is owed, "don't watch Dish, except for the free preview channels". But NFLHD will be gone soon.
...(c) If "Better TV for All" is that important, then maybe get a "pay as you go Dish system".
Good Luck,
PS - Dish does not activate/deactivate the dish antenna, just the receivers.
