Mahindra And Mahindra — body paint vanishing and screws got rusting

Address:

Kannur, Kerala, 670002

I brought xuv500 2 month back in august 2018, my vehicle numbers is KL-59-S-6001, and the case number is MA1YU2WTUJ6F18092. I find out that the body paint is vanishing and the screws are got rusting, in that rust the the yellow color spreed to the body. the body front bummer is not fixed properly .
i complaint to the service provider ERAM MOTOR in KANNUR, KERALA, when put the vehicle for first service they told me they recover and replace the things.now its 65 days no responds come yet . service provider or Mahindra cheated us .This the way you treat the customer, lot of other brands are there in market but only mahindra is not caring the customer properly.
im still worried that the car use cheap screw and get rusting, the car cost 17 lakhs -
i talked to service head but he told me they replace the thing, after the service no calls got from Mahindra service point .
can you please report it show the people, dont trust mahindra
