This guy called and I answered - he mentioned that he was coming out to clean air ducts. I said that I don't want air ducts cleaned and to take me off his list. He asked when was the last time I got my air ducts cleaned and I told him again I did not want it done. He said "we will call you back again" - I told him not to call me again that I was on the "donotcall" list and he argued that this was an epa requirement - I repeated not to call again and hung up. I'm reporting these guys.
