I ordered redmi 6 pro from mi app on 16 april 2019 around 9 pm. The phone that i ordered was black in colour, 3gb ram which i bought for rs.8999. The product reached today on 19 april. But the product which i received today was old and tampered and the seal was broken. The phone itself was in a pretty rough condition. I, hereby want to exchange my product as soon as possible.
