Poor pathetic ****mers

My dishwasher pump broke. Contacted Appliance Repair Clinic. They gave me a quote, for the same price as a new dishwasher. I rejected it. The tech then offers to do the do off the books, for half the price. He then apparently fitted a new pump, and then suddenly, everything else on the dishwasher stopped working. Can't switch off, change programs, and pump not working. He then tried to bypass wires so that it can work. Still not working. He then gave me the so called faulty pump that he took out. The problem is that the pump he gave me is not the pump from the dishwasher. The broken pump was not removed. I then had to wait for a couple of hours before trying to switch on or off the machine. End of story, they fried the circuit board. They would have came back to fix, but I am still waiting. It is a week now. So i think they quote people so high, so that they will take the off the books deal, which then means that there is no 6 month guarantee on their work. They are ****mers and if you value your life and your house. Stay as far away from them as possible.
