Myntra.com — Return rejected in quality check

I ordered sneakers on Feb 16th 2022 with Order ID # 1196908 [protected] in myntra. I found size was misfit and initiated return on the delivered date itself...i.e., Feb 17th ...And the Myntra agent picked it up on Feb 18th...All the tags are intact. And the product is as it was. But I got update that my return was rejected during quality check...I refuse to believe it. This would definitely not happen. Please help me in this issue. And there is no explanation why the product is rejected during quality check. Please help.
