Adidas — Refund not received from Adidas.co.in

I ordered an Adidas bag from their official website on Cash on Delivery.
However, I did not like the quality of the bag, so I returned it after 2-3 days.

But, I have not received a refund from them even after raising the issue 2-3 times with their team.

I contacted their customer support team, they gave me a form to fill. I have filled out the form but haven't received the refund yet.
