Reliance Trends — return issue

Address:

Haridwar, Uttarakhand, 247667

My order was partially delivered so i got all my products on different different days. On one my 2 t-shirts came and at the same time the courier boy asked for the product to be returned. So i hand over the product to be returned to him. But he didn't gave any receipt for the return to me. He picked it on 11 or 12 june. It's been many days i didn't get any msg regarding that product. So i called him on his number and asked for that returned product.
Now the courier facility and courier boy too are refusing that they hadn't picked any product from me. I forwarded them those msgs which i received before and after the pickup. But again they are refusing.
What do i do now???
