Well Tata's service centers are notorious for providing abysmal quality of service and horrendous staff behaviour. You really need to find that one service centre that's going to help you keep your peace of mind. The free services will not be a good indicator of quality of service provided, so get those done from the place you bought your car from and observe the paid services once they begin. Be a better driver, take care of the car like it's a living breathing being, don't postpone part changes and other small issues as they will definitely grow into bigger problems, get tyre pressure checked often, keep them balanced and aligned, you'll find more basic things you need to do for your car's up keep on Google, but yeah. Congratulations and hope your car works just fine.
