Hedy did not service me. I had this guy name David. He told me extra rules I didn't see when choosing location. and there's no dust pan. furniture was old and had cob webs. lastly the main areas of the house don't have ac. the AC is only in the bed rooms. not exactly what was stated at first. I even put new batteries of my own to see if that worked and it didn't. so due to no air flow we had to open windows and were smoking outside but due to the open windows the smoke went into the house. we were not smoking in the house. even though I didn't see any rules against that either.
