Reliance Trends — reliance trends I didn't get my return product amount

Website:

www.reliancetrends.com

I bought Some items (Please refer the attached photo below) Order ID : TR06281120 from https://www.reliancetrends.com by Cash on delivery but the delivered item was entirely different from i ordered. color, size and even i got a T-shirt which was not in my order.
the girls top also was different one.

So i returned those items with Return Id: 00358045
and it was picked up for return, till date i didnt got the money back.

but my main Concern is that i ordered these items along with other items which was delivered correctly total for Rs. 2793 using reliance trends coupon of Rs.1000, it was the mistake from Reliancetrends.com so i f i get the money back as Trends credits Did i get the Discount of Rs. 919.40 (which is clearly mention in the attached screenshot below) which was got when i purchased below items.

"my time, my effort and my cash for puchasing those items was a waste and even that reliance trends coupon also was cheating one"

So please do favourable Solution for my issue.
