Amazon India — Wrong item delivered need refund

Address:

bangalore

Hi,
This is Akansha Pal. On 21-may-2021 I received the wrong item (mama earth tea tree pack with the invoice bill with the order number both are attached below). The Two items which I had ordered were
Mamaearth Vitamin C Skincare Facial Kit (Vitamin C - Face Wash 100ml + Face Toner 200ml + Face Cream 50g) and Mamaearth Onion Duo For Hair Fall Control: Onion Hair Oil 250 ml + Onion Shampoo 400 ml
(Screenshots for confirmed delivery in Amazon as such order number mentioned on top attached below) and the mail for items to get delivered before receiving the wrong item. screenshot attached.
On the same day, I made a call to amazon customer care regarding this issue, they told me that the Product is not returnable and informed me that they had filed the investigation and asked me to call on 27-may-2021 to know the status of my order.

Therefore, 27-may-2021 again I made a call with customer care. They informed me that investigation towards my issue had been denied, and I will not get any refund.
The items I ordered were for Rs. 1, 670/- and the wrong product which I received was for Rs. 499/-.
On call they suggested me to write a mail to [protected]@amazon.in regarding my issue... And it might help me.. I did the same i wrote the mail with all screenshots I had (mail screenshot attached). The next day i got a mail from amazon.in (screenshot attached) and here again they asked me to reach them with any live medium.
I had also connected with the chat medium from their website but it was not helpful.
I got the invoice bill for the wrong item with my name and address(screenshot attached). order number is different with the original Product order number. i have attached the mail screenshot where the order is highlighted which is different with the invoice i received.

And they had 10 days return policy... Which they fully used up with their investigation circulation. After ten days i was not able to connect with them. Because it got vanished.

I am requesting you to please look into this matter and help me to get my refund ASAP.

Thanks & Regards,
Akansha Pal
