Sly, dishonest and not reputable dealership

I will probably get a 'thank you' response, if any as I went as far as the Ombudsman but unfortunately they don't have the mandate to punish dealerships like this but I promised them I will let the world know what dishonest ****** they are. The very short version of this story is this: the car was advertised with a full service history. Luckily I took a screenshot of it otherwise they would have denied it. They could not provide the service book and had a whole lot of stories which I never believed. After 6 weeks the gears for the parking break breaks. They deal with it, give me a curtesy car but all is not well as they provide me with a service book with information that a lot of the services cannot be substantiated. The last service was also not done and more than 1 person's opinion was that the parking break issue could have been avoided if it was serviced properly. I threatened to take them to MIOSA. After I lodged the complaint and I kept on pushing it came to light that there is no supporting information for the details in the book - which in my eyes is *****. Some of it was also incorrect. Their explanation to MIOSA was that it was a system problem that did not list the car properly, but that is bull**** as they had 3 months to tell me this instead of keeping me on the line with 'trying to get the information'. They also refused to contribute towards the blown speakers that I replaced, which I reported the day after purchase. And the car did not have a boot cover, which was a deal breaker for us. They provided us with a 2nd hand one which did not fit properly instead of buying a new one that would have cost R10k. This was also never sorted. They wanted to take out a service plan to keep me happy and let the sales rep pay for it, how is that fair?? The sales rep contributed R500 towards the speakers out of his own pocket, how is that fair?? Oh and they sell you an extended warranty where the actual premium is only about 25% of the amount that you pay. And when you have the audacity to raise your concerns on a Legal group on facebook about this, you get a call from them to take down the post as we don't know how the structure works. Yet when I cancel the policy and they give me the calculations of the amount to be refunded, it is exactly as I stated it - as per the schedule. And might I add that the owner & DP is very arrogant. But I guess that how you act when you know you're in the wrong. After 4 months I sold my car, one of the reasons being I did not want to own a car provided by them.
