Andhia Sasan Nimapara,Dist-puri,Odisha,pin-752106

My poco X3 pro phone bought on Flipkart big billion days sale on 2021 is dead after 1.2 years on December 30. Next day I submitted to MI care offline. They returned to me today saying that it was dead & rejected couldn't be repaired. Poco extended warranty to 1.6yrs still offline care said even if we solve ur problem, this gonna charge me coz I bought it online. Bought with offers at 16500rs, now can't even afford in short time a new handset. Please help in exchanging the worst item
