Called about their advertisement for 37.09 unlimited duct cleaning. Called to cancel the day before. They came a anyway. When the rep came he counted the ducts and then tried to tell me the charge would be over 500. I quested the price and he started taking off services to lower the price. When I told him I would not use his service he called his office. They tried to strong arm me into paying a 50.00 fee. I refused they said they would send it to collections. When I tried to speak to the office would not allow me to speak and ultimately told me to go f myself...do not use these guys
