Adidas — Refund rs 2000 not processed

I Placed an order with Adidas which was delivered to me on 22nd april 2022. Due to an issue with the quality and size, I immediately raised a return request with Adidas, the order was finally picked up by the courier partner on 24th of april.since it was a cash on delivery order, the refund was to be done on the respective bank account. But till now i didn't get any mail or message asking my bank details. So i tried to reach them through their customer service in all the ways possible but none of them worked. Due to a fault at their end, I cannot keep waiting for the refund especially of an
amount of Rs2000. Kindly assist in resolving the issue.
The order number for the respective order was:
AIN00711707
