Yup, same experience here 3 months trying to make them understand "he is dead".

We left their crap in a room for ~6 months total at the advise of his estate lawyer. Eventually they did accept that he was dead and canceled the account as well as sent a box to send the equipment back.

They got their equipment back after it had all had an unexpected encounter with a hammer. Never heard a peep about it.

I think they went bankrupt, so hope that's some consolation. I heard that an attempt to buy them by DTV got rejected on antitrust. But in the article it said they went bust

Surprisingly, neither Dish nor DirectTV has gone bankrupt. Satellites are pretty capital-intensive. They both faced challenges over the years but have managed to skate by. AT&T kept DirectTV afloat for quite a while. The proposed DirectTV + Dish merger fell apart for multiple reasons. While the government didn't explicitly reject it, there was a lot of uncertainty about whether they would bless it. The deal also required Dish's bondholders to voluntarily write off a chunk of their debt, which they ultimately got cold feet about.
