Adidas — Regarding refund of shoes already returned

Dear sir/ madam
I Placed an order with Adidas which was delivered to me on April 1st 2023 and I did payment by cash rupees 2000 .Due to an issue with the size of the product that was ordered, I immediately raised a return request with Adidas was quickly picked up by the courier partner on 2nd April 2023 .
Since then adidas did not ask me for my bank details or any details for refund . I have called over customer care number so many times but no one ever picks up infact I emailed them twice and received two different responses one said I have received a credit note in my account which I haven't received moreover in the other e mail they wrote that the refund will be processed in my bank account in 7-10 day but they haven't even for my bank details . Adidas did not even ask for my bank details where would they refund the money? . I have attached the screen shot of the order too.
Kindly assist in resolving the issue.
