My elderly mother received a call from this number.  The man knew her address and name and said he would drop by to discuss some paperwork.  She could not remember the details, but we were all worried and instructed her not to open the door and if he called again to contact one of her daughters.  No idea who this is, what they want with my elderly mother, or what 'paperwork' he was after.  Scary that he knew her address and was going to drop by.
