I've been a customer of Coan Oil for 24 years. Recently, I inquired about their "Cash for Clunkers Furnace" program based on a brochure they sent me. After leaving several messages on the office phone of the furnace sales representative, I finally received a return call on his cell phone. After asking him a very basic question about whether a new furnace would burn at a higher temperature and emit less ash on my rooftop, his cell phone suddenly went dead and he never bothered to call me back. I issued a complaint to the main office and have never received a response.
