Popular Maruti — Multiple complaint after servicing

I had given my vittaara breeza, 2021 Dec. Model, to Popular Maruti at Kelkatlai, Chennai, because of damage made by dogs in the wiring harness In April. When they delivered the vehicle the engine got stopped inside the workshop itself. Later, they made it working. Next day, the car got break down and they took the vehicle to the workshop and repaired. But, the instrument cluster, defogger etc is not functioning as before. There is starting trouble also. I am contacting popular to get the issues rectified. But, they ask me to bring the vehicle and nothing was done. They come and say some stories to brainwash me.
Kindly take action to get the issues rectified.
