Ajio — Product not picked up yet and CC unresponsive

I placed an order(two shirts) on 29th Apr 2022 and it got delivered on 7th May. I did not like the size and fit of the second shirt (Blue) and decided to return it. The return request got canceled stating that I was unresponsive and when I contacted customer care they promised to get it picked up by 24th May. Unfortunately, they were unsuccessful again. When contacted again they told me that I have to return the item by myself and after further questioning, they started to ignore the calls.

Request you to kindly look into this on priority
