I have given the vehicle (Octavia 2018) in calicut authorised service centre for complaint of showing coolant warning sign first they took more than 35 days to make the parts available in that authorised service centre i again gave the vehicle on 12th of nov and after 12 days when i went to deliver the serviced vehicle they said the coolant showing sign was rectified but now its showing engine warning sign and they are they don't know what the real issue is they can't make it correct and more weird reply like they need another same car to check the exact problem and i have to arrange another same vehicle!! What am i supposed to do now??
