Amazon India — not fulfilled the delivery of the order

I ordered a rakhi from amazon on 1st aug 2019 at 12.30 am which was showing a expected delivery date of 13 aug 2019. After that i received a email that the item has been dispatched on 1st aug 10.30 am. After that i didn't receive a single email. I was tracking the shipment which only showed the status as shipped and even on 13th aug it was showing as "arriving today".
But the package did not arrive even after the expected delivery date and amazon initiated a refund without giving a proper reason for the non delivery of the product. Festivals like rakhi is o[censored]tmost importance for anyone and by not able to cater to the orders they are hurting the feelings and sentiments. If they are not able to deliver a order they should inform beforehand so that at least people are left with an option to order again or look for an alternative. When an order is nowhere close to delivery still amazon waits for the last day and finally what they do is initiate a refund. People will get there money back but the occasion they had been waiting for will not come back. The happiness, the main purpose of celebration depends on that product which is not delivered. It will just look like a technical fault or just another order which cannot be fulfilled but one will not understand the emotions behind them and how it ruins a festival or occasion, the gift send by brother may reach her sister but rakhi send by sister does not reach his brother. Just a mere refund does not help. So amazon should take the effort to verify the seller, remove the sellers whose track records are not good and take the responsibility to deliver the orders placed, not just accept payments and refund them.
