Ajio — Refund of courier charges not returned.

Address: 161 - A BLOCK, SRILA HEIGHTS,, St. John Road, East nehru Nagar, East Marredpally

My Order# FN[protected], I was being instructed to self ship the product if I dont wish to keep the product. and then promised that the same refund of courier charges would be refunded to me after receiving the product.
I have received the refund of the products but courier charges are not yet refunded.
SInce past 7 days i am being following up, still havent received any resolution.
They informed me that by 25th May, they will resolve the issue and then extended to 27th May 2022 and now still saying more 2 days.

I dont think they have any intention to refund the courier charges i paid on behalf of Ajio and which they promised to return me
