Hi i have purchased tata tiago xz (O) model car from gajanand motors palanpur gujarat in first week of feb. Month. While i got paid receipt for extended warranty it shown name with someone else. While i inquired in gajanand motor they don't have any satisfactory answer and said that in first service it will change the name. After that call comming from tata that you have 5 months passes and you didn't come for service while i purchased a month before.

My question is this new one car purchase is already second hand saled to me? Why online vehicle is not on my name and with somebody else name? What is the scandal? Even after completed all formalities and got the vehicle.
