Bad workmanship

On 4 September 2019, my bakkie blown gasket in Bloemfontein. I was referred to Jonathan, the owner of this company, who is the biggest **** and unqualified mechanic I ever met!!! He promised me that my vehicle would be fixed within 4 days (engine overhaul)and I had to wait 2 months 10 days to have it back after numerous calls, sms's and fights. He is very rude and stole most of the engine parts within 3 days of working on the vehicle. He however replaced the parst and upon receiving my vehicle which drove less the 50 km, it broke down again, resulting in more expenses on my side, the engine must again be overhauled, I now had to replace the battery and alternator. The alternator he installed overcharged the battery which resulted in the battery to blow. He gave me a 3 month or 10 000 km guarantee on work done, he refused to take any of my calls or respond to my text messages on the day my vehicle broke down. Till this day, he still does not take any of my calls. I paid him for services rendered and this is the treatment I got. His contact details are *** resides at 10 Einstein, Heidedal, Bloemfontein.
