Comment: The technition was very informative and offered some reasons for the long term problems with our carpet. He is the only tech that has tried to really get the carpet clean,,,,He was dal-worths last chance with me although I have been a customer for many years. He was here two to three times longer than the last ones you sent and he did a 100% better job. It's been a couple of weeks now and we are very happy with the job he did.
