Address: 411013

I have ordered two jeans which are very loose and different shade. Now i want to return my product.. And i requested to return and myntra was showing it will be pick up within a one day but it's been 4 days still no one came to pick.. Next week i m going out of town.. Now tell me how will i return those things if i won't be here.. Also i want my refund back as soon as possible as i m going out of town.. If they don't pick up till then i wont be getting any refund.. Not expected this kind of service from myntra..
