Adidas — Refund money not processed

Website:

www.adidas.co.in

Hello, I am Sagar,
I ordered shoes from the adidas app on 19th April.
Order amount:- ₹2399
The quality was not upto the mark and the shoe size was small so I returned the order on 22nd April. It was a Cash on Delivery order. I filled the form for the account details on 22nd April and got a confirmation and refund initiate email for the same on the same day. The returned item was received by adidas on 27th April. And they initiated the refund process then. But it's been more than
20 days and I haven't received my refund yet.

During this time I talked to the customer service agent 2-3 times and they asked me to wait as my refund is in process.
But when i called them again on 16th May again they told me that my account details haven't been updated and I have to fill the refund form again and wait for 14 days again. It's been 20 days already and 14 more days now.
I can't wait that much for my money.
Kindly assist me in resolving the issue.
