When I first read, “The tv didn’t work,” I thought it was going to be another case of her hitting wrong buttons on the remote. Too bad it wasn’t. That would have been an easier fix than what you had to deal with! What a mess! At least it sounds like you got them all working again.
Something had to have happened to the provider during the day, because every caller for tech help got the recording before waiting to talk to a tech guy.
They are all working now. And if it happens again, I know to start with unplugging.
