I received three phone calls with caller ID "& B P K". They were 412-856-8258, 412-856-8447 and 412-856-7206. According to one of the posts for the other 2 numbers the company is American Windows in Monroeville, PA. There are 2 Ameican Windows listed in the Yellow Pages, both are in Pittsburgh, not Monroeville. The map that came up when I did a reverse number lookup puts the phones in downtown Pittsburgh, at 4th & Grant.
