Received a call today from this number.  They wanted me to give them my address without offering any additional information in return. I refused.  I kept asking what the call was in regards to and they wouldn't answer me.  I asked if they had an address on file for me?  If so, tell me what it is and I will verify if it is correct or not.  They would not do that.  I finally said put it in writing and mail it to me.  If you have the correct address it will reach me and we can go from there.  Otherwise I have nothing else to say.  And I hung up.
