Who called from 6109954517

The usual scenario. No name in caller ID; just said PENNSYLVANIA. I did not pick up. Caller left no voicemail.

received a call this evening.  caller left no message.  caller ID says "Wayne, PA"

for some reason this caller managed to bypass all my switchboard and auto attendant and got straight through to my direct line. He asked for me by name and said that he was calling from North American Chimney. When I redialed the number it was not in service. I think that this is a private detective acting on behalf of a bill collector not a chimney sweep
