Audi A 3

I have an Audi A 3 Sportback 1.8T which i bought through the dealership mentioned above.<br> after a week of driving i started experiencing that the vehicle is leaking oil. i took the car back to the dealership explaining to them that the vehicle is leaking oil. They then said they will fix it which i got my car back the same day. Then after a few weeks it then started to leak oil again out of the exhaust and my display is telling me that i should not exceed the maximum of 4000 RPM. so i took the car back ton the dealership on the 29th of august so it can be fixed i took it early because i was going on leave the 11Th of September so that my car can be fixed by then. so form the 29th of august till today i have not been pushing them or rushing them i left it after them keep on telling me different dates of when i will receive my car. they postponed the date abiut four time and i still have not received the vehicle. i am frustrated and very angry at the moment if i do not get n my car by the 11th of September the morning they will pay my fees for my holiday.<br> <br> They don't phone me back when they say they are going to happened about 5 times when i phone them they don't answer.
