I keep getting phone calls on my voice mail but never try to talk to me directly. If I answer they hang up. Don't recognize this number an I'm not under attack by bill collect either. One call was from some guy claiming g he worked for the IRS an he was going to send the police an I have recorded the call.. I said go a head I will be here waiting... Seems like there scripted as they don't really listen to what your really saying to the them. The guy said Can I "Read" from you. What the hell.. At least they should learn to speak proper grammar..I usually block an don't play any head games with them. That would annoy them likely. Cell phones aren't protected anymore... I  have  spy ware blocks on my phone.. Getting towards Christmas we will get even more calls in an out of the country. I have a Telecommunitions friend that runs the numbers for me an he said don't banter with them. Report the number an block it..
