Savan Retailers Private Limited — I'm complaining about product bought by you.

Dear sir,
I'm the trusted user of Flipcart since last 4 years. Recently I bought new infinix turbo 12 phone on July 29. But it's display colour was spreaded now. Within one month I'm unable to use the phone. When I visit the authourised infinix service center they told that it costs[protected]. But the product still on warranty period. What can I do sir? Kindly help me?
