Amazon India — non delivery of product due to diwali rush

Address:	411057
Website:	www.amazon.in

I placed an order for an apple laptop on 20th oct'19. I got a mail saying delivery will be on 23rd dec'19. On 23rd, after trying to reach the delivery person (Whose number was shared in the email from amazon) throughout the day, he finally answered and was vexed with me. He said he was in leave that day and hence was avoiding my calls. I apologized and mentioned i was calling him as his number was shared by amazon. He said somebody else would deliver. So i waited till 9:30 p. M. At my office (Since that was the address i'd asked the delivery at) and as soon as i left, i get an sms saying delivery was attempted but failed because i was not available! I called up customer service who assured me it will be delivered the next day, 24th oct'19.
On 24th, i got a message sharing a delivery person's number who when i reached him said he wasn't the right person and have me the number of the delivery person from the previous day. I tried reaching the delivery person and he kept me waiting the entire day saying he would be coming in a bit. Every time i called, he would say how he's almost there. Finally at 5:30 in the evening he says he doesn't have my laptop with him for delivery! Then i get the sms saying 2nd delivery attempt failed!!!
I call up customer service again and am assured, yet again, that the laptop will be delivered the next day, 25th oct'19. I mentioned that i will be traveling on 25th evening and going out of town and was rest assured that the laptop will be delivered.
I start off 25th morning by calling customer service at 7:00 a. M. Reiterating that i need the delivery before evening as i would be unavoidable post that for a few days. I checked off they could deliver the laptop to me at the another address (To where is he traveling) but apparently that wasn't possible either. Assurance again that it will reach me.
I called up again in the afternoon twice and was assured it would reach me on the "next couple of hours". Needless to say, there was no delivery made and by now the app mentioned the status as 'contact customer service'. So i called them back and was answered by the escalation manager who after a lot of arguing assured me she'd try to create a replacement order and change the address to the alternate one and have it delivered bwfire 30th oct'19. She said she'd just drop me an email confirming this.
After waiting for over 20 hours, i called back again and this time spoke to another escalation manager who after a lot of argument and "i understand, but..." just cut the call on me when i insisted that i either get a solution or be connected to the next in escalation hierarchy! Oh, and get this, she said the escalation manager from the previous night had lied to me!
I've recorded these calls but am so frustrated with the overall attitude! There's not an iota of "service" extended to the customer. There are false delivery updates made and internal conflicts brought out. Someone should do something about this or just let amazon take on the load it can handle rather than tell customers, "kya kare, diwali hai na. Bahut problems hai orders manage karne mein!"
