Millivisions Marketing Pvt Ltd - Defective tyres sold and noresponse after damage

I purchased * tyres of Pirelli make from millivisions marketing pvt ltd for an Audi car on **-**-****. On **-**-** one tyre bursted while driving on a highway and when complained the company gave a reply stating it is due to impact and does not cover under warranty. Again on **-**-**** I observed a bubble on another tyre and company gave the same reply and avoided to address the issue. Later I realised that they sold me tyres that are * years old and when I questioned, they stopped replying to calls also.
