10 months later and my car still isn't right

My vehicle was dropped off for some fabrication work in August22. They quoted me an amount that was not cheap and it was the second time my car went there. On collecting the car a week later, I found issues that were not present before. More specifically, engine fault codes. I attempted to tune the car on the day that I picked up only to be told that there is an issue. The vehicle switched off on the dyno. Now, 10 months later and around R25k down the road, the car is still not right. I had the ecu finally tested by ecu express who confirmed that the ecu is damaged beyond repair. I have no firm proof but here are the facts: > issues with misfire and starting that was not present before dropping the car off > jannie senior had, at the time, just bought the same car as mine with a blown motor because of ecu issues > I have a whatsapp conversation with Jannie jnr where I ask home to check with his contact for another ecu asking him not to mention that it's for me. He says in the conversation, but the supplier will know its for me. This was very suspicious and when I asked him how well the supplier know, he never answered. PEOPLE, PLEASE SAVE YOURSELF FROM THESE GUYS. YOU WILL BE BETTER OFF NEVER MEETING THEM
