Amazon India — regarding package delivery

I had made an order, order no:[protected], has to be delivered by 28 september by 8 pm but the order hasnt been delivered till now. I am seriously very much dissapointed from this type of service from amazon, these type of retailers are putting amazon's name down, its been 2 days and i haven't received my phone. I know how much it is important for me that phone that i ordered i wanted that very ungently but your delivery service is seriously awful. I just cant explain my anger. This is all what i can say, i dont have any other words to explain your awful service.
