Unexceptable bad service

Problem with composting machine bought from Jarnsmior.co.za Owner JD Telephone number ***

I bought a composting machine from Jansmior. I paid the deposit of R67620.00 on 27 September 2019, and the final payment of R68080.00 on 12 November 2019. They said it will take 20 working days from the day of deposit. I paid for the transport on 13 November 2019, R6325.00 and received the composting machine late November. When it arrived, there was something wrong with the machine, a part they had to order. We waited 2 weeks for it. After that was fixed the machine worked for a few hours. I had to call the guy several times, and when I phoned the office the called me back. He sends somebody who had no clue of the machine. After a lot more calls he came to look at the machine, and the told my brother and the farm manager that there is a manufacturing fault on the machine. That day I told him he must take the machine and give my money back. Now we were already in January. The did some welding and said he fixed it. The machine worked for about a day, Since then I got a guy in Bloemfontein to try and fix the machine, but without any luck. The eventually send a mechanic on 28 February who did more welding and said the machine is good. It worked for 2 days. Now the drum bursted and it is a huge safety hazard for humans and animals at the moment. We got complains from the neighbours and they are threatening us with the health department. Our vet also expressed her concern about the health and safety of the humans and animals. This guy must return my money and take his faulty machine back. It is costing us a lot of money on disinfectants to try and keep the place as hygienic as possible. I also had to hire a TLB twice to dig holes to get rid of the rotten meat. Can you assist me asap.
