I am getting these calls too. Spoke to someone at Greenbelt, they say it is a mailbox at Verizon. Just checked, number is now disconnected, guess they changed their number. My provider says the only thing they can do is change my number to make the calls stop. Guess thats what I'll have to do. What a pain.
I have been getting at least 7 calls a day from this number and the two times I answered they knew my name and told me they understood I was looking to earn extra income saying that they were a company called International Travel. The last time the guy told me he found this out from somewhere online so I asked him where. He did not know! So I told him I am not interested and to stop calling me...So we'll see?
