Wicked Rides (Pretoria North)

I took an Yamaha XT 200 for a fitment and installation of a CDi unit. Delivered the bike on Tuesday 15 September 2020 at their premises, 634 Preident Steyn Street, Pretoria North. I received a call from the mechanic on Wednesday telling me that he had a ride with the bike, the bike is performing well, what must he do? I told him about the faulty CDi unit that is not working in cold conditions. The next day I received a call telling me that the bike's engine got stuck. They have to open it and access what is wrong. Soon after that they send me photos of broken gears and a broken clutch basket, and I must come and pick up the bike. I delivered a bike in working condition and get a broken one back, and they don't except any responsibility for their amateurish deeds. Damages to the bike, parts only, amounts to R5 600.
