What I do when I get an unsolicited phone call :  I made a voodoo doll, you can look up on line how to make one. Every time I get a call like this I stick a pin in the doll, I  hope it does them harm, I know it does me good.  Maybe if a million people made voodoo doll and we all kept sticking pins in them they would die. Its worth a try.

Called yesterday.  I didn't answer and they left no message.  CID was "VETS NOW"
