JSW MG Motors India Pvt Ltd - My MG Astor Car pickup Lag issue

I've purchased the Car on February *th
****. There is a manufacturing or design defect with the car that the CAR is not
giving pickup or lagging a lot on *nd/
*rd and *th Gear. If you are cruising at a speed of ** km/Hr and brake the vehicle. It doesn't give proper pick up on the same (*th Gear) and lower gear (*rd gear). On Ghat areas its performance is dropping to very low. Only *st gear is working.
Its not able to give pick up or not able
to climb the Ghat road on *nd Gear. I
had a Hyundai Grand i** sportz variant of ****cc, it was able to pick up at the
same *nd and *rd gear where as Mg astor having ****cc engine is unable to climb on *nd gear and need to use *st gear with high acceleration to climb the Ghat road. The Manual transmission of this Car is having a lot of engine defects like pick up lag and all.
The Transmission of the Car is not good and having a lot of pick up issues.
I want MG motors to resolve the Gear Pick-up issue and take Back my Car.
