Worst Dealership!

I bought a Polo GT which looked good on pictures but had dents in reality which I didn't mind. After only 3 weeks the car's dashboard was signalling temperature and I had to carry a 5 litre water bottle like I'm driving a 30 year old car! It started overheating and I towed it back and they said I should email my towing invoice which I did and still did not get any feedback till today. It's been a week now without it and they say they it will take two weeks to fix a simple mechanical issue! The car blew the head cylinder gasket I know and I have bought old cars and never did they break after 3 weeks. Their warranty is a lie. The Receptionist just **** to me saying she emailed me details regarding progress on my car but I wish I had checked Hello Peter reviews before going there. I wish to erect a billboard to warn people NOT to go there and I will go to great lengths to expose their ***** & ***** dealership until they learn to treat people or close the shop.
