Incurence

I bought a car what good service, picked up the car the Friday afternoon. Car eng was misfiring. They said must to ook it to the people who work on the car. Around the corner from the Dome. I phone the mechanic first to explain. He said must put petrol so I did R600. The car was stil misfiring. He told me to. Bring in the car. They were about 2km away. Took of the cover over eng. And when they took out no 3 coilpack it's was wet. The cleaned all coil packs and put masj on eng still it shows silinder 2 and 3 were misfiring. The car had red coilpacks in. They put 2 black ones the car were much better. I took it Hom but it did not perform. Like gti 6 were supose. About ****m before my service the car had loud notice in motor. About 100 m from. My house. I stopped and took it in to gerage we buy cars told me. After few days I phoned the person in charged and he said it Wil take 3 to 4 weaks to give me a report but there was no compression on piston no 1. He said it Wil cost about 96000 to fix. But my incurence we buy cars gave me will not paid because the cars turbo was upgraded. So went back to them towed car back to my house. Went and bought a std motor for 48000. But I spoke everyday to people from we buy cars. It take them 2 weeks to respond and said they Wil. Pay only 50% of my lost. They want letter from bosch to say the motor was upgraded. What was wrong. 1 week from now they say got letter. And will pay. But they never say when. Why did they sold a car to me that were upgraded and why did they sold a incurence to me if they knew I am not covered. I am not happy and the not honest to theire customers. Once car sold its your problem why.
