Good car with worst service

Had a very bad experience with Tata dealership. Booked the car the same day I took a test drive. Later I found out I have been cheated by the dealer. I have all the evidence of my booking. The people at the showroom were very very unprofessional and they are very good at lying. The car has a good build quality with VFM features at the price point. The ride quality and mileage is also good.
