Extremely Pathetic service From NTT Volkswagen Kimberley!!

Disgraced at the terrible service shown by Ntt vw Kimberley. I asked for my thermostat and shocks to be checked, i also asked for a quote on full car inspection and was told that the more things they check the more expensive so i said to keep it at checking the thermostat and shocks. They phoned me to conclude that my coolant bottle was the problem and charged me four thousand three hundred and odd for a new water bottle! They assured me its the water bottle after i asked are they sure it's not the thermostat, and they said yes, once you replace the bottle your problem will be solved. Not even 2 min out the dealership the problem persisted, i took it back the next morning 7am and explained, Foreman Jp told me he will check, phones me the evening to say its the thermostat is faulty, i say that is what i came for in the beginning. He wants to charge me another R6111.00 like i am some *** that is ready to be milked!!! Told him to speak to his manager and explain that i was **** to, and they fixed something that wasnt asked to be checked, i stated even if the bottle was broken i never asked to check the water bottle but the thermostat which they obviously never did and checked my bottle when i got told the more checks the more expensive!!! They contradict themselves. I take the problem to the dealership manager who says he sympathises with me and has a solution, a week later (mind my car is with them the whole time and i am a area manager who needs his car for work every day to travel to 5 outlets daily)lets me know he cannot do much as the dealership principal says i must pay, i go to this dealership principal who was apparently busy selling a car to a client when i asked where he was only to insist on seeing him and find he was busy with nobody, then explain my case again, and he tells me a story about his iPhone that if he takes it to apple and says the speaker is faulty and they say it's because the phone needs a software update and they charge him R2000 and the problem persists that he cannot request a refund as they will tell him the phone needed the update, and that he cannot do anything for free, i stated, when i came here your *********** people assured me it wasnt the thermostat, that fixing the bottle will resolve the issue, i paid cash and because i never knew they dont accept cash they used the principals card to pay and gave him the cash, i asked does he remember, he said yes, i said i paid in full! What on earth did i ask for free. I took the case to Vw sa when i saw that the entire management from the ground up to the top is rotten(couldnt care about the client who must suffer because of their mistakes!!!), who dragged it another week (without my car), to only let me know they cannot do anything as they are a private dealership!!! By now i am so upset. Then i went to MIOSA and opened a case and fetched my car. I am utterly disgusted at the pathetic service, i cannot express this enough, i do not have anything against any race, but when i am made to feel treated differently because of my skin colour being indian, by a Group of people who all share the same skin colour then i cant help but feel it is a matter of race, whether they meant it or not that is how their actions have led me to feel seeing that their entire management is white, My stepdad is White, i have nothing against any race but when treated like trash... When asked for my documents to present my case to the ombudsman they refused to give it to me, promised to send via email, the 10 days have lapsed and no email. Well done to them!. If this is how people are treated i wish to never return to this pathetic place. I always looked at Volkswagen as a brand to be respected but now my view is tarnished. I am exhausted for fighting against a broken system.
