Myntra.com — Missing kalini product

I had placed return request on March 30, and the product was picked up on March 31 . I received a message sayIng did not pass the quality check . haven’t received the product nor refund .
What is this quality check ? It is convenient to say did not pass the quality check. When in truth all the tags and bill was intact ..
pls ship the product back or refund the amount .
These irresponsible behaviour make us the consumer think is it worth shopping from you .
