These are the same guys as 907-550-9800. I bet my paycheck that is a scam. If you only get one ring and a hang up it most likely because they call multiple people at once and take the first call that is picked up. Here is a link to the Federal trade Commission website that might help get rid of these jerks:
I have got a total of 6 calls in the last 2 hours and have not picked up the phone once before I was hung up on. If these guys called you please report it some how. I am going to post this message on the other page also.
