Called and asked son inappropriate identifying questions, then told him to go study and hung up.

called my unlisted number, asked for me by name on the machine, i picked up and he said now you pick up when it's over and then hung up. CREEP he did not answer when i called the number back

Someone called from this number but never answered

Got a call from this #. Male asked for my wife, by name. When asked who was calling he said, "John Glen", and hung up before my wife could get on. I attempted to call back, got a recording saying "no directory available for this line, please dial your extention now or call back". No company name given on the recording. Very strange!

had a call from this number at 9pm at night.  when i told them they woke up my son and it is 9pm the guy corrected me by saying it was 8:51pm.  I told him i dont care it is late and he woke up my son.  He did mention he was from the Fertnal Order of Police.  
caller id says illinois call 708-794-3253.
I jsut did file a complaint with the do not call list.
