They were cleaning the neighbor's house and their machine is extremely loud and disturbing all of the neighbors. So I call the owner and he laughs at me telling me that he has been doing it for 25 years and that is how the machines are supposed to be and then he hangs up on me. Well we have had reputable companies do vacuum services for neighbors and you can't hear them over the normal noise in your house. It's sad the way the owner represents himself and his company!
