Unsatisfactory Audi SA

I bought an 2013 Audi A4 1.8T SE (110000km) on the 23/08/2018 at Audi East Rand. I bought the warranty and all needed to extend and cover if there are mechanical issues. I took for 120000km service at Audi Mbombela on the 05/10/2018. In the first week of December 2018 it had cooling issues, it was towed to Audi Northcliff, I didn't the joy with regards to warranty cover, of which I towed it again to Audi East Rand where I bought 3 months earlier. I had a chat prior with the Salesman with regards to the car breaking within 3 months and warranty he sold me only paying 60% of the R21k quote. He asked me to bring it so it can be fixed, they took and called me to fetch it as it was fixed. I took it in for 130000km service at Audi West Rand, the day after it showed coolant signage on the screen and the pipes were broken. I then took it again for 150000km service on 29/11/2019, the day after it showed the same issues, broken pipes, thermostat, the whole thing. I called Audi Assist I didn't get any help, I eventually called my warranty on the 01/12/2019 and they sent a tow truck to pick the car up and they sent it to Audi Welkom. I have contacted that the damage is R22k (see similar quote a year ago above) and warranty will pay R10k. I asked for the quote, it showed me the same things that appeared last year, and the day after it been to service. I got hold of a copy of "Vehicle Service History" which showed me this vehicle has chronic issues with cooling system: 83480km = Replace Thermostat, 90878km = Piston Cooling Valve, 91661km = Coolant Pipe (this is all prior to me purchasing the vehicle) and the thread above shows you what I have inherited or blinded into. I would like Audi to address this matter at their earliest convenience as I'm going on holiday with my family and currently my fiance don't have transport to travel to work. Regards
