New SUPERB a great looking car but is worse than even a push cart

well I bought the new petrol superb in march 2009. Initially the ac gave me a lot of trouble . Numerous trips to the workshop and certain part changed finally ac was repaired to some extent. Rear passangers still sweat. Now the car done 7500kms suddenly stopped in middle of road in delhi on 9th august night. Car could not be started, moved or pushed. Finally next morning the car had to be towed. Now I am worried abot my family's safety and security in this car. What if this had happened at high speed or on a highway. Worse still what if had been overtaking at that point of time on a highway. To my surprise one of the senior skoda india officer gave a surprisingly inhuman reply that they are not concerned with this issue. Initially because of ac problem car spent more than 2 weeks in workshop. now for current joj it already has been a week and skoda sya that will take minimum 10 more days. On my telling them to refund my money or vhange the car they do not even reply to my mails. A new so called luxory car spwnds nearly 25%  of time of imitial ownership in workshop AMAZING QUALITY!!!!!!!fair fuel economy, great styleAc is not good specially for rear and reliabilty of the car is ZERO
