Amazon India — delay in delivery and not notifying whereabouts

I ordered an item and recieved a message informing that it will be arriving on a particular day but in vain. Now itz past the delivery date and when i enquired about it i was told that it will be arriving on a particular day but it hasn't. Then again i enquired about the same and was informed that it will be arriving on another day. I have already paid for the item and this is the result! Atleat be kind enough to notify the whereabouts, which to be honest you are not doing. Kindly find me a solution for this. Its the 2nd time i am facing this. I have yet another item ordered will this be the situation then also?

P. S - please don't dissapoint your customers or else you will be losing many customers soon.
