I had one of their pushy salesmen in my house offering me a discount if I decided on the spot. That is a big alarm bell there.
They called me back a few months later to see if they could 'enter my name in a drawing for $15,000 worth of new windows' and give me another quote. When I politely said 'no thank you', the guy said 'Sheesh' in a really pissy voice and hung up.
This bad behavior is after they have been told to clean up their act. It seems my instincts were spot-on. I would not risk being a victim of ""unfair and deceptive acts"":
