REPAIRSPARK advertises on the web but I can NOT recommend this business to anyone

REPAIRSPARK advertises on the web but I can NOT recommend this business to anyone. I called them (Collen) re. a problem with my Bosch washing machine last week. They quoted R3500, to replace the computer. I had no basis to argue this. They took the machine, returned it two days later, pushed it into its space without leveling it. So it jumps around when spinning. I paid R3500 on delivery without proof of job done, and without being able to test it through a full cycle. The guy was in a hurry for payment - had more deliveries after dark. I only discovered two days later on first use that the machine was noisy when spinning and leaned to the left. I sent them a Whatsapp video with the machine in action jumping and noisy. Nothing happened. Several follow-up calls were not answered. I am 74, unable to level the machine myself Their attitude strengthens my suspicion that an old lady might have been taken for a ride w.rt the diagnosis too.
