no idea i answered they said nothing......

calling and not speaking.

Received call.  Didn't answer.  They didn't leave a message.

I called back It says "Where sorry you have reached the number that has been disconnected or no longer in service"

Asked if I needed to have my vents cleaned.  When I said "no", he asked if I needed any work done around the house.  I said "I don't need anything done, and I'm on the do not call list." He hung up.
