Very very bad after sale service

I bought a brand new JMC Vigus 5 a few months ago from JMC East Rand. With a fitted Tonneau cover. I worked with Garth. He delivered the vehicle to me in Hectorspruit. We found a few faults. 2 bumps on the rear of the vehicle and a spray paint fault on the roof. HE then torn the tonneau cover. He promised to sort it out. But after a few months and the first service none of the faults were repaired. I then took the cover in. I had to drive from Hectorspruit to their offices and I made arrangements with Garth to fetch the cover on Sunday. He first agreed and then later turned around and said he doesn’t work on Sundays. Even though he was the one who torn the cover. Garth then promised that he will deliver the cover to us in hectorspruit on the following Wednesday, but since Wednesday everyday we speak to him the delivery date is pushed on. When I phoned him he became very rude and told me I must come and get the cover myself and he put the phone down in my ear. They make promises they can’t keep. This is the second JMC I’m buying and both dealerships had very very bad after sale service. And with all this no attempt was made to fix the rest of the faults.
