Tata Safari — Ac problem

Address:

Singrauli, Madhya Pradesh

I have been facing repetitive ac failure with my tata safari storme. I have had ac unit completely changed at tata service centre multiple times, but just after a few days from repair, ac again stops working
I have spend more than 200000 on ac repairs alone! And the vehicle hasnt even driven 150000 km!
Every time after repair, I get an assurance that problem is resolved. But it never actually is.
We only have one vehicle in our family, and my dad, who is 58 years old, is frequent traveller by road. In this heat wave, its criminal to make someone travel without ac when he has spend more than 12-13 lakhs for this vehicle.
