I faced great problem with return and refund policy of amazon. I ordered tempered glass and cover of mi max mobile. But the glass they send were smaller than the screen. So, I asked them to take it back. But they told that they can’t pick it up rather I have to post it. This is one problem. Another one is with the return of back cover which is slippery. They told that they will puck up the back cover. But it was since six day they are saying this. I don’t know what to do. My money is also blocked.
