Triple T Appliance Repair Tech

Hired Triple T Appliance Repair five years ago to fix a badly shaking dryer and he did a great job - lint needed to be cleaned out and the blower wheel had been thrown out of balance from lint causing the shaking. Five years later and the same problem returned. We tried to clean out as much lint through the lint trap but it wasn't good enough so I called Triple T again. He arrived on schedule, took off the front panel and door, inspected everything and cleaned it out. Then he said he couldn't put it back together as he had somehow damaged a connector on the front panel on one of the control boards. He said he would take the board with him as he had a technician who repaired these things for him, and that he would have the board back to us and reinstall it in one or two days, tops - for no extra charge. Over two weeks later - after numerous text and voice mail messages - Triple T never showed up until I asked him to return the parts he took - these parts were worth well over $500 new. The parts then appeared at our front door, early the next morning with no knock on the door. Anyway, I took a close look at the board, saw that 4 pins on the connector in question were slightly bent, easily straightened them in 2 seconds, re-inserted the plastic retainer on the pins, and it was fixed just like that - perfectly. Triple T could have easily done it himself when he was here. Anyway, in re-installing the front and top panels I also had several extra screws left over and subsequently found that Triple T had removed several screws unnecessarily - forcing me to remove the panels again, inspect the inside frame carefully and reinstall all of the extra screws back into their correct locations. What I don't understand is how a technician who was so great five years ago could turn into a major disappointment five years later - servicing the very same issue on the very same appliance!
