Worst place to buy a car in the World

I bought a 2008 Opel Corsa 1.8 sport in May 2014. Upon delivery myself and Michael noted on the delivery inspection list a couple of issues that needs to be resolved. The vehicle was advertised as full house, The Airconditioning unit didn't work. Capital auto world agreed to regas the system and get it working. I was instructed to take my vehicle to Capital Auto wold's mechanic in Johannesburg west, so i did. The Air con had some parts that was blocked and needed to be replaced, it was replaced at my cost. The mechanic claimed against my Advance motor plan, again a plan i paid for to maintain my vehicle after the purchase not to repair it. Air con parts was swapped out for second hand parts stripped from a s**** vehicle in the yard. Air con worked for a week and not been working since. Capital Auto world refuse to fix the problem. During the past year i have spend over R10 000 on repairs on this vehicle(shocks, brakes, engine repairs) repairs that should have been noted by Deckra as the car was supposedly there for inspection. I WANT MY AIR CON FIXED!!! My lawyers advised me that i have a strong case! So fix the problem false advertisers and ************!!
