Myntra.com — Return Item not picked up since a long time

I have ordered a product (Libas Women Green & Gold Zari Woven Design Straight Kurta with Trousers & With Dupatta) from Myntra. Due to fit issues, I placed an exchange request, but no one called or came to pick up the item and deliver a new item in exchange. I followed up with customer care and spoke to supervisors as well multiple times. But there was no resolution. When I realized it isn't helping me, I asked the supervisor to place a return request on the product instead. The supervisor cancelled the exchange request and placed a return request on my behalf on July 4th. He mentioned the item would be picked up within 3 days. But no one called or came for pickup. I kept on calling customer care after 3 days. Everytime I call they say wait for 48 hrs and nothing happens in 48 hrs. I don't have trust in Myntra any more. They are not telling me the root cause on why the product isn't getting picked up or why no one is calling me. The have wasted my time and money. My product is still not picked up and I lost my money. I want Myntra to refund my money back.
