Tata Motors — Car not starting from 2 days and nobody came

Purchased a TATA Altroz Car 2 months ago in Visakhapatnam. It is not starting from 2 days. Called the central helpline number who said they will arrange a call back immediately but nobody came. I called again and they don't seem to have a log of my previous complaint and took all the details again and promised to send someone immediately. That immediately became 2 days now and nobody came. Called again and se situation again. This is like a loop. Not sure what would be the situation if this happens somewhere on the road in between cities. Pathetic customer care. Did not expect from TATA
