Rec'd several calls from this number and numbers similar, they asked to speak with me and then verify my address so that they can ensure they were talking to the right person, I told them that they were calling me and to let me know what address they had for me on file and then I can let them know if they had the correct address, when I did that, the person hung up...Sorry but I am not just going to give my address to anyone.  Prior to that I asked them what it was regarding and he just said its a business matter.
