Amazon India — Ordered 2 soaps and its not delivered from more than 20 days! WORST!!

Address:

AMAZON INDIA, ONLINE SHOPPING

I had ordered 2qty of the same soap and it is not delivered since 20days then what is the use of being a Prime customer by paying ₹1000/- per year?? If prime customers are treated like this then what about others? That too i had paid it online for the products while placing the order itself.
(Attached screenshots of their commitments)
28th July i had placed the order and Estimated delivery was 1st August then after 1st Aug came they said it would be reattempted shortly in another 3days after that they didnt commit any date and its now only showing that its being late so you can either wait or cancel!!

Are they making customers fool??? Or customers are fool to wait this long to cancel their order and wait for refund???
Making customer wait for 20days and then saying to cancel is a very worst behaviour of Amazon and i m going to raise this issue very seriously. That is the reason i m bringing this issue to consumer complaints forum so that immediate serious actions will be taken on Amazon.
