if they sent out the same model then there is no contract extension...they replaced the one that died
Seriously...do this...call back and right away say RETENTION....you will get retention who knows what the hell to do and will fix it. You have had more issues in the last week with them than I have had in the last 2 1/2 years (which has been no issues honestly)
I'm certainly going to do this tomorrow right after work. After my mom waited 3 hours I called DirecTV and finally got the receiver activated.
However, now there is another problem.

My mom now sees a blue banner at the bottom saying no signal on sat 2 which is because only 1 coax is coming from the dish since it is an old system. With the first DVR only 1 coax was attached to SAT 1 and no connection on SAT 2 and it worked fine. Is there a menu item to disable SAT 2?
