Engine rebuild gone wrong

My dealings with this company started in January 2023 when he took my Jeeps motor from PMB in KZN for a complete rebuild with a turn around time of 2 to 3 weeks. I got a motor from them in April 2023 with many parts missing and some definitely not mine. This was installed by a local company and when started it had no oil pressure. If I have to judge the quality of their work by this motor it is bad. Mr. Meintjes then took my complete vehicle to his workshop in May 2023. There is a long history of calls asking for my Jeep to be completed. Never have I heard so many excuses, staff, oil leaks, key programming and the list goes on and on. It is now August 2026, three and a half years later and I still cannot get him to complete it. Every time I speak to him I get the same story, we are busy with it.
