Amazon India — delivery system of amazon

Address:

Gautam Buddh Nagar, Uttar Pradesh, 495001

I ordered a product from amazon with cod option. The delivery guy came and told me to use cards when i said i have cash and i have used cod option he started fighting that "my amazon account should be linked with aadhar, don't you listen narendra modi!!!", he also said amazon has set new rules. I mean what is this?? He refused to give me my order so i told him to go back then finally he give me my product with cash.

Please go through this issue seriously, i have attached the delivery report. This is completely unacceptable behavior of delivery guy and rule of amazon (If that is!!!).
Ps : i tried to mail amazon at the given website suggested by amazon itself for customer complaints but msg was sent back to me saying service not available, how are we supposed to complain without a properly working amazon mail id? Screenshots are duly attached as proof.

Asmita
