Flipkart 99% of the time dont give the exchange value which they show at the time of placing order. Three of my friends have faced the same issue in past few months.
I bought F6 on the launch day sale, Poco claimed 2 yr warranty for people who bought on the launch day. But in the FK invoice only one year warranty is mentioned.
I raised a case with poco customer care but did not get any positive reply from them.
