Bad experience with the car

The trauma I'm facing with my Renault kiger engine zen Amt 😱 it's my 1st car and the experience has been totally unpleasant 🤞 Bought it 5th April 2025 at 17000km, same month end it displayed "engine fault" and wouldn't start until I removed a battery terminal and put it back (using my hand) took it to renault Eastrand and apparently they changed a switch. Problem continued, took it to renault springs and apparently it was the gearbox. Few days later same problem.. At this point I don't know what to do coz I'm a woman who travels with girl kids and I honestly can't afford to be stuck by the side of the road like that. I don't enjoy driving my blue joy anymore 😭
