Michelin India — Torn tyres

I am writing this letter to bring to your notice a very crucial issue that needs your attention as a matter o[censored]rgency.
I drive Toyota Innova Crysta and I recently got 2 sets of new tyres of Michelin from a local dealer for it
I used to buy Bridgestone tyres for my car but this time I decided to get Michelin tyres by getting impressed by your Tv commercial advertisement and one of the local tyre dealers as it says that we get a very smooth and cushioning performance from Michelin.
Recently 1 of the tyres went out of air suddenly and then when I saw it there was a crack on the side wall.
And again after somedays another tyre got crack on sidewall itself while I was travelling on the highway.
Spending so much money on the tyres for smooth performance instead of getting these types of problems isn’t affordable to me.
Therefore, it is requested to please notice this because this is life-threatening, and safety is our priority. Would you please see to this matter and respond to it.
I am looking forward to your cooperation. I shall be very thankful to you. Anxiously waiting for your prompt action.
