Before purchasing my Groupon, I called Massey & Woods to confirm that I should/could purchase 2 since I have 2 dryers in my home. They confirmed so I did. I scheduled for the following week between 9-11. The tech never showed up until 11:40. She immediately told me that it was only one per household per the "fine print", in which I said that her company had instructed me to purchase 2. Then she went turned on the dryers and came back inside with a picture of 2 vents side by side that she said were not opening at all which means they are terribly clogged. I told her the upstairs dryer vents out of the roof, so I'm not sure what she is looking at. She also proceeded to take the hose of the dryer and vac it out and then stood in the room with the dryer and the vac running, but every time I went by she didn't appear to be doing anything. She said if I wanted the vent cleaned from the house to the outside it would be another $169 dollars for each dryer and that what with a $20 discount. I told her forget it, I could have vacuumed the dryer hose myself. Then she proceeded to drag her huge vacuum up my wood stairs. The following day I had a reputable company come out, the vent she was looking at was not even the dryer vent at all! It was the biggest scam of a Groupon, and they had no business sending out a girl who obviously had no idea what she was doing.
