This person (male) keeps calling and if I answer hangs up, if I do not answer he leaves a detailed message for me to call back on the above number , claiming he is calling from a post office and has a package for me and that I must call to get my package. Number comes up as 'unknown' on my phone. He has called about 6 times and hung up when my mother quizzed him about who he is. Now I reject calls, it is obviously some kind of scam. Person claims to be George McFry.
