The other day Dish Network cut off 3 of my 4 receivers. They left me a message to call an 888 number. I called from work and they said that in order to reactivate the receives I have to be on the phone with them and read back a series of numbers to them that they send through to the receivers. They said that they periodically audit customer's receivers. What are they up to? I don't have the receivers hooked up to phone lines as there are no phone jacks near the receivers and one of them in is my camper. The guy on the phone said that it was no big deal that they are not hooked up to a phone line. Any advice is appreciated as to what is going on.
