Hi Skoda, I have Skoda rapid 2019 model. Last month we had accident. And my car is now is Skoda service center near kuddlu gate, electronic city bangalore. N9w they are asking for parking charges per day-500 and estimation charges 18 k. How can they ask for estimation charges.is there any rule/ write in paper. They are harassing us . Skoda service in india is too bad. They are estimated 8 lacs. My car value is 8 lacs. On which basis they are estimating. They are not helping us.
