Myntra.com — Return not being picked up from delivery address

I've ordered a Roadster co-ord set from Myntra recently and I didn't like the dress and wanted to return but when I put a request it said I should self ship the product. If they are providing door delivery why can't they pick up the item from here? This is not fair I want the product to be picked from where it has been delivered.
