They called twice, half an hour apart. I was away from my phone but see the two calls listed under "Recents". Clairton PA? Never heard of that place, don't know anyone in that area.
Called did not leave message. When I returned the call, the first option was if you would like to be put on this number's do not call list, press 1. I didn't press 1 because I was curious as to who/what it was. Then it said "all circuits are busy, please try your call again later." Not sure what it is, but probably not anything that I'd consider important I'm guessing.
