Tata Motors — paint bubbles

Address:

Mumbai City, Maharashtra, 400022

I bought a new tigor xz model 3 days back. While taking the delivery of car i found a bubble on front right fendor and i ask the same to the concern person there but that doesn't work. His assistance was not satisfactory. Now i am worried of that panel will become rusty. There is no point of such things when you are buying a brand new car.
I am done with this and want a replacement or a job done on my car.
I am fed-up with this car..
