I have grand i10, my car damage from front side when I bang to big stone, now my car in the showroom from last 15 day and here tata aig officer did servey and they are not allow some work to do while it damaged in the accident. I am sick of this service of tata aig. For sure i'll not renew for insurance with Tata aig and will not recommend this service to anyone. The bonnat is shaking too much how can I take my car in this condition even showroom people also saying that we have to chance that bonnat cover but these insurance people not listening my words. Really worst service I have ever seen, Please help me, even staff is not co- operating, nobody picks up call when I call them not answer well, they are so rude while talk.
