I placed an order 2 days before upto now my order not delivered and it is delayed to 5 days in order tracking its displayed on 20th dec will get order and taking long time process to get order in amazon.
I mailed to amazon they saying hsve to wait for 20th december. But while placing an order it showed 16th december get delivered. I can't understand why amazon people are bluffing customers and delaying order only prime customers can get 1 day delivery. But for normal customers it takes only 2 days. But its more than 2 days to get my order after 5 days. This shows very irresponsible service and became worst services of amazon.
