Ajio — Can't return the order since 11 days Ive got it

I have received my order on 20th April 2021 and since I’ve to return the product, it’s saying order not yet delivered, I called the customer executives a lot, the response is always same “WAIT FOR 2 more days”
I’ve been patiently quite since 11 days, how to return the products back if there’s no return option for it.

I’ll share snapshot, do check it, it’s in packed since 14th April, and I received it on 20th, but not marked as delivered.
