This number called my SKYPE number 3 times within one hour. They did not leave a message.  (NOTE: I use a standard - not a personal greeting).  I *67-ed them from a landline to find out who they were.  A man with a heavy accent said "FEDERAL GRANTS DEPARTMENT how can I help you?"  .......I let him say this three times without saying a word - hoping that I could catch some background noises or otherwise. Background noise consisted of shuffling papers and another phone ringing. This is a total scam and I guess now they are working their way through the SKYPE numbers.  Avoid this mess........blocked!
