Adidas — Not refunded money

I have placed an order on adidas and the order was delivered on 2/08/2022
and the next day delivery person came and take the product and it was approved by the warehouse and then they request a refund via cash on delivery as my payment option was also cash on delivery and the refund amount was
2 998.50. On website of adidas its showing it may take upto 14 days to refund but its now 27/08/2022. I am also trying to call there customer care number but the line was closed. The email id the was logged in adidas website was: [protected]@gmail.com. Please solve my issue as soon as possible.
