Amazon India — I have returned a product but not got the money back

Address:	713213
Website:	Amazon.in

I have ordered a cooling pad, but it was not of appropriate size as mentioned in product details, so i returned it to the address provided by the company, but still not got the refund money (Rs 1575) and shipment charges (Rs 500). I have attached the copy of mail in which the details are there in pdf format. The mail contains the address provided by "amazon.in" and proof of returning the product to that address with images of product and courier invoice.

It's been 1 month from the date of product purchased, i have also filed a claim for refund, still no action taken. I want my money back immediately.

So please take serious action urgently.
