Worst service Audi CT

Worst experience ever! I have taken my car in 28x times in the past few years same problem. No power, car cuts, oil problems. Car totally cuts out when I’m driving serious risk to everyone on the road and my family in the car. Engine warning light constantly on, oil consumption problems constant .. I get told that it cuts out as their was a previous tracker they did not know this was previously installed in the car.. really !!!... Today car goes in once again comes out with two warning engine lights and jerking. 8pm waiting for Audi assist once again..It went in for oil consumption no warning lights on snd went for a service two weeks ago. Audi let’s their woman staff drive in the rain with a car in this condition and thinks it’s acceptable to give it back to me in this condition.. worse than I gave it to them. To let a woman drive a car in this condition and thinks it’s acceptable is Disgusting how they treat woman and their service is extremely poor. Iv bought 3 x Audi from them and the dealer principal is useless no help at all after numerous mails and calls!
