Myntra.com — return item not been picked up in almost three weeks

Address: South Goa, Goa, 403711

I placed a return request for a defective item i purchased on the 11th september via cod. I submitted all necessary pictures etc. But no one called to confirm pick up. Then 20th the request was cancelled without any reason being given. I immediately raised another return request. It is now the 25th september and my item has not yet been picked up. When i called customer care they said they can only raise another pick up request and it will take another five days. Myntra or their courier services responsible for such delays should be penalised for such delays.
