I have gotten a couple calls from 307-459-2990 this evening as well. When I looked up the number, it is telling me that it is coming out of Cheyene, WY. I also received calls from 219-865-9027 and it says from Dyer, IN.
I received a call from this number tonight at 7:49 pm CST, it rang three times and hung up. When I called the number back I received an automated messaging stating "extention 1000 is not available" and asking me to leave a message. I did, I advised them I was on the "Do Not Call" list and if they called my number again I would sue them for harrasment.
Somehow my number got out and I now have SIX different numbers that call me at least every 30 minutes everyday and they are all spam. It's ridiculous. I finally answered this number today and they asked if they could speak to "Beth." I told them they had the wrong number and hung up. Getting the number blocked this afternoon.
This may work for some or all of you: If your phone carried or cable company phone carrier has a spot on their website for "Call Blocking" then place this number on it and that should work.
