Bad service and no after service

My Land Rover Discovery 3 died on me last year, I had to wait be for doing the repairs as I first needed to get the money together. I was sent out of Country by my work and ask my wife to get this guy to help as she needed the vehicle. she called Mr De Beer and he told her that it is only Injectors. They collected the vehicle on 13/11/2024. They drove the vehicle onto the lowbed trailer and took it away. A few days later they told us that the engine has broken stuff on the inside and that they need to remove the engine. after removal they discovered that the engine has broken conrods and needs to get overhauled. which would cost us around R64720. which was all good at that stage. then later he told us that the engine had a hole in the block on an oil channel. (they drove the car out of my Yard and there was no oil leaking from the vehicle). I do not completely understand that but kept quiet as we needed the vehicle urgently. Eventually it ended up with a lot of extra things that was added to the invoice and the last invoice was a total of R102170. we kept quiet and paid the money because this is my primary transport to work. Even though we told Mr De Beer that we need the vehicle urgently because it is our primary transport it still took him until 12/02/2025 to complete the work. we received the invoice and could not pay the last R10000 as we were running short of the money. we made an arrangement to pay the money by 25/02/2025 and did pay. Then we still had to wait till 26/02/2025 to receive the vehicle. This guy gives no feedback, does not do a proper job on your vehicle, I only drove 780 km sine the engine overhaul with my car and then the engine just cuts out again and does not want to start now, seems like it seized up now. I contacted him 3 times since the car broke down and he promise to come and look but never pitches. Really really bad service
