Myntra.com — pickup of the product done by courier person and updated wrong

Address: 121004

Hi,
I ordered a few shoe pairs from myntra but had to return them due to some issues with the products..the courier person picked up the product but updated wrong that pickup has not been done. I lodged a complaint on Myntra for this but got a resolution that pickup has not been done. It clearly indicates that something is done in between by the courier person. I need a proper resolution for this. This is not fair on part of Myntra to not take any action on this. I need my money back.
