I wish I was exaggerating when I said that this was the worst customer service I have ever received. I am NOT. The furnace was installed incorrect, and when I asked Stuart to come and fix it, he ignored multiple phone calls, text messages, and kept brushing us off for over SIX months! He cares about you right up until you pay, as I have read other reviews. Because him fixing the install does not pay him anything, he has no interest in doing it. He also belittled, and insulted me on the phone.
