Myntra.com — black solid bag o[censored]nited colours of benetton

Approximately 2 weeks ago i placed a order of black solid backpack o[censored]nited colours of benneton from myntra shopping app
I got these product on time but somehow quality was worst so i placed return and refund request.
So next day my product was picked up from my home. I provided them my paytm payments bank account details for refund. But its more than a week i am not able to get my refund. Such a pathetic service from myntra.
