This is regarding order #AIN01173824
I placed an order for a pair of shoes, which I returned. The payment was made via google pay on delivery mode. Pick up process is completed and I got a mail on 6th August 2022 stating that I will get the refund within 7 working days.
Today is 23rd August 2022, and the refund still has not been initiated. The customer support lines are continuously engaged or everyone has left for the day. I wrote 2 emails today, one asking them to look into the matter, and the second was a forward of the "we've received your returned Adidas items" email that I received on the 6th of August. The value of the returned product was Rs. 4, 199/-
