Third!!!!!!! Dish Network illegal (pre-recorded) call TODAY. The first 2 were on my unlisted cellphone! See http://whocalled.us/comment/818-870-8183 and http://whocalled.us/comment/818-887-8183 (which was accidentally the wrong number entered into whocalled.us) for legal references, and URLs to information on the web. This time, I was quick to hit "1" when offered. I was congenial with the guy who answered, but insistant that I wanted to know if it was Dish Networks or a hired service FOR Dish Networks that he was working for. He insisted that it was actually Dish Networks, and then was immediately replaced with a recorded announcement that the number had been removed from their calling list. (I never got the chance to ask to be removed).
