Tata Motors — Tiago Vehicle suddenly stopped

I have a tata tiago amt Vehicle (2020 august model ) which on drive suddenly looses power, then the instrument cluster turns off and then car doesnt start.
The roadside assistance number was called and after keeping me in wait for 4 hours told me that they will not be able to help me asked me to arrange a tow myself.
I got support from local police who helped me to get vehicle started and next day i brought it to malayalam motors service center, vazhakala, kerala, they said its a earthing wiring issue.
I see that many users have faced this kind of fuel pump issues earlier and the service center fails to acknowledge it.

The roadside assistance was just a bogus with no help. Totally un reliable
