Tata Motors — cheating customer by false claims & poor servicing

Address:

Tata Motors, 4th KM, Rampur Road, Bareilly 243502

I have purchased a TATA Nexon EV on 10th April, and followed all the process required. I informed the team that I am an NRI and would be moving out soon, and hence all formalities to be done in 2-3 days max and they aligned for it. But currently i am still waiting for the charger installation and there is no feedback from team - "sir we are working to have it done asap". Also while driving my car to show how to drive, they hit the car, and done temporary paint. I still was ok, that they can do the painting later but still lot of hastles here.

Major concern :
Tata Nexon claims : 465 Km in City mode and ~ 350 Km in Sports mode in the manual. My car in Sports mode didnt ran 200 Km even and even in City mode it is below 250 km. - If you are highlighting that i should drive with X, Y, Z why this is not written in your manual and why this is not highlighted to customer on purchase. While India is expanding in infrastructure to improve in global speed ranking, Tata is delivering next gen cars with speed limit to max 80 Km/hr to meet the claims. This is purely cheating for the customer, and hence this should be relooked or my car to be revalidated to ensure whats highlighted as performance is delivered.
