Ecom Express — regarding the delivery of the product that I ordered in amazon

I ordered a book in Amazon which is supposed to be delivered by today 14/08/2019.but the delivery boy took it yesterday and contacted me I told him all the details and my address he called me and said that he cant come to my location for door step delivary..I asked the reason he said that he have to go elsewhere for delivary..subsequently I complained in Amazon and ECOM EXPRESS, After complaining the delivary boy contacted me and said me to come half way to collect the product which I rejected...following this incident I complained in ECOM EXPRESS, the executive told me that she will do the arrangements to deliver my product yesterday itself ie 13/08/2019..but nothing happened...when I called E COM EXPRESS Today for knowing the status of my delivary the executive didn't even show the courtesy to listen to me and hung the call...and now I am in the middle of no where and doesnt know anything about the status of product...
NOTE: This is the 2 time I am facing problem with the delivary boy...especially there attitude towards the coustomer..and reluctance towards delivering the product doorstep.it is understandable If the terrain is bad but in my case they are absolutely fine...when ever i call me them thet are telling me it's raining, in the same rain they are going 10, 15 km forward for delivary same day...
