Yesterday I received a call from Dish (at least I think it was Dish). They asked if I have had signal problems lately. I told them every once in a while I get a signal loss message and also the receiver reboots on its own but not often enough for me to worry about it - maybe once every week or two. The service rep, who already had my name, address and telephone number said they would send someone out next Tuesday between 8:00am and noon to check things out. I told her it was not really necessary because the signal loss is infrequent and probably won't be evident when the technicians get here and the odds are that everything will be working properly. She said that even infrequent signal loss should be checked out and it will be at no charge to me. She "sounded" okay and not suspicious but does Dish do this sort of thing without the customer even complaining about a problem? I am concerned only because sometimes legitimate DishTV repair people come out here in trucks that are not marked with the Dish logo. I am not suspicious of them because I am the one who called. This on the other hand was unsolicited. Does this sound legit?
