Myntra.com — Sofa cover not picked since more then a month

Address:

C 303, Faculty Flats, Amity University, Panchgaon, Manesar, Gurgaon

I have ordered 2 Cortina sofa covers of charcoal grey colour from Myntra together but I was delivered light grey items. I have recieved wrong product and I had been requesting for the pickup since 27th September.
After one month of constantly complaining, they picked up one of the sofa covers. The second one is yet not picked. When they were bought together, delivered together, then why are they not picked together and why is it not picked till now??
Everyday, I chat with the Myntra customer care and they say they have raised a ticket but they literally do nothing about it.
I want them to pick the product and refund my money back asap. This is a way of harassing the customers and actions should be taken against these kind of scams.
