Called at 7:57pm. Diverted by a service I subscribe to that intercepts robo-dialed calls (rhymes with SoNoHobo). I called back (*67) and a man picked up and said "Hello," which leads me to suspect it is, what, the 20th different number used to solicit funds for the Fraternal Order of Police — but not really, otherwise the called ID would not say "Unavailable." Of course I hung up on him.
Yep, just got two an hour apart. I looked at my caller ID logs and this number calls me at least once/day. Fortunately, I never answer any calls from numbers I don't know. They can call all they want, I'll never answer.
