Mahindra has worst customer care and warranty service.

I bought my Mahindra Pick up s11 in 2020. I had to take the vehicle back for a re-call on the gearbox instruckted by Mahindra Sa. The end of 2022 I had gearbox issue the vehicle broke down next to the road, took it to dealership they claimed the issue was resolved. Since the first issue up to now it has not been resolved. The vehicle has been to 3 different dealerships to sort out the same problem.The longest time I didn't have the vehicle was for 6weeks. Imagine not having a vehicle for 6 weeks that you are paying for. Each time I have to get the vehicle there and back to the dealership for this gearbox issue and it takes weeks to get it back. So I gave Mahindra customer care a call asking for assistance because the vehicle is still under warranty and it's been back 4 times for the repair on the same issue. They aren't willing to help me with a car nor willing to help get the vehicle back to the dealership, it also feels like they rather trying to wait till my warranty runs out at the rate things are going. I also asked for an extension on the warranty for the gearbox but no answer. Please if someone can help I'll appreciate it because I don't know what to do anymore.
