Is DISH network acting weird for anyone else?

We’ve had repair techs out twice, no help; when you try to change or recall channels it either takes forever to happen or, when you get the channel, it displays an error message saying that either

a) the satellite signal has been lost and is being reacquired,
b) you aren’t authorized to watch this (local!) channel, or
c) you should reset the system.

And then you may get an apology screen, telling you they’re working on fixing the problem and it’s not your fault—except that nobody on the help line seems to know what I’m talking about when I tell them that! AAARGH!
