Poor pathetic customer service from Tableview Home Appliances!

Our Whirlpool Dishwasher were giving error messages. We decided to take the machine to Tableview Home Appliances for a report. After the initial report they mentioned that the magnetic wash motor needs to be repaired and the machine to be serviced. We received the machine back on 23/06/2020 and informed that the machine was functioning correctly now and invoiced. A week later the machine shut down completely, on which we were told to bring it back to their workshop. I was advised that the motor needs to be replaced. Another week lapsed and after calling them to get feedback, I was now advised that the motor was replaced, but due to the intricacy of the machine, it is malfunctioning again. I had to wait another 2 - 3 weeks for a proper (correct) motor that they now have ordered. They however fixed the motor so that it would function in the interim. When we installed the machine at home, we noticed that the metallic door had quite significant markings, which were not there before it was taken to them. It looks as if the metallic layer on the edges of the door was sc****d off. We did not notice this as the machine stood in the sun outside when it was collected. When opening the door, it inclines to the right which it never did before. The door was also tight when opening and closing, which it never did before. We contacted Whirlpool (KIC) to assess the machine and the feedback indicates that the motor is functioning now normally at this stage, however the original door was replaced, the serial number supports this statement.

We wrote to Mr Banks at Tableview Home Appliances via e-mail on 29 July 2020 to question the damages and the replacement of the door, as we were told by KIC's technician that the door was replaced and that it was not necessary if they only repaired the motor. To date we have had NO response from Tableview Home Appliances, even sending another e-mail to them on 5 August 2020. All we want is to have the matter resolved amicably. This is the worst service that I ever encountered! This practice is not acceptable, as they were not honest in the manner which they conducted themselves.
