I share my personal experience with you guys. .
I booked mobile from amazon they show delivery date 30 th of August and I booked at 25 th of August. But my package is delivered at 27 th of August that amazon is alway delivered before due date. Bit unfortunately my device was defect one. So I request to refund my bucks and take your product back they come next day and pick up my product nd my money was refund in an hour from picked up time.
So moral is they are very fast service
They are trust ful
They are very great online seller that I ever visited .
