This company called me FOUR TIMES on 1/15/15, even though I asked them not to call me again every time they called. Then they called me AGAIN the following day. I again told them to put me on their Do Not Call list and not to call me again. They are trying to tell me that my furnace needs to be serviced again. They have NEVER serviced my furnace, nor have they done any work at my house. I am complaining to the FCC re the Do Not Call violations. I would never do any business with someone who is as scammy as these people.
