Adidas — Not getting refund money

Order No. AIN00733654
Order placed on 28 april 2022
Order returned on 2nd may 2022
It’s been around 15 days Since I’ve completed my return process but I haven’t received the refund yet.
I contacted adidas several times Through mail, chat, call and messenger services but to no avail. Nobody replies to the mails. There is no one on the chat services. customer service care of adidas is worst. Refund amount for my order is 3999/-.

I would really need my refund as soon as possible.
