I got a call from this number right after I hung up with AT&T. I answered it right away and no one was there, and no voice mail was left. My guess is that this number knew that I was inquiring about internet service from a competitor.
You need to call the customer service number which is 800 531-5000. They will deny that they they call you, but will still put you on their do not call list. Oh and guess what the person you speak to is probaly not going to be from this country so you will need to explain yourself carefully.
I have been receiving calls from this #, I finally called back today since I am tired of it and they said it was about information I had requested on their website, when I got to talk to a csr, they said it was about an offer, I inquired what type of offer, he said there were many but wanted my credit card #, when I said I did not requested anything they put me on hold and did not come back.Oh, by the way, they claimed to be Dish Network, I think it is a fraud, because they did not even ask for verification of any type, only for my credit card.
