Adidas — Refund not processed for two returned tshirts

I have returned two tshirts to adidas warehouse, that I bought from adidas website itself. Now those are with them as per the mail I have recieved an email on 12th April 2023.
Order no.s AIN02917328, AIN02919947.
Those were 'cash on delivery' orders, so as they are not having my bank details to refund with them, I have not got any follow up mail asking for bank details to refund my amount. Its 21st April today and I have not got my amount of any follow up mail, asking for my bank details. Please look into this matter. 599+749 = 1348 INR is my refund amount for two tshirts.
