The Mr. Appliance tech came when he said he would. Prior to arrival, he sent a message to my mobile with his name and photo so I knew who would arrive at our door. He was professional, made his diagnosis, compiled a costed-out estimate and could accept an initial payment for the diagnostic call by credit card. When the part arrived, he again came when he said he would and got it installed and working with no fuss. Final payment, exactly as per the estimate, was also by credit card.
