Myntra.com — Pending refund of 4 Portico Quilts

Hi,

I purchased 5 Portico quilts from Myntra in November. I returned all of them, and the packages were unopened. The products were packed in a zip bag and then wrapped with a plastic on top. I dod not even remove the plastic, let alone open the zip and take out the product. So the items were completely untouched by me.
The items were picked up Myntra Logistics partner-Delhivery, and the same was updated on my app.
A few days later, it showed that the refund was processed for only 1 quilt, while the return request for the remaining 4 items was denied, the reason being cited that the products failed quality check. Hence, my refund was also denied.
Now, the issue is that since the products were completely unopened, and the same was noted by the person picking up the products I don't see how it could fail quality check. The only way that could happen was if either it was tampered with during return logistics, or it was faulty products that were shipped to me. Either way, the onus does not lie on me.
Also, if the return was not accepted, then at least the products should be shipped back to me, but even that hasn't been done. Thus, neither do I have my refund, nor my money.
I have filed a complaint about the same with Myntra but to no avail. It has almost been a month now but the only update I get is that they are trying to get in touch with their Logistics partner, and thus request for 48 hours to get back to me. And once those 48 hours are up, I get tje same email, requesting 48 hours more. And so it goes on.
It has been highly frustrating as there is no response from their end other than this. I don't know if I will get the refund, or my products back. They are highly unresponsive and seem to be bent upon cheating the customer.

Hope to find a resolution soon.
