Myntra.com — refund

I have not received refund of 1479 even after returning the product. It's been more than 1 month they have not refunded me the amount. My bank & google pay support team have confirmed that the refund has not been credited in my bank account. Myntra has not taken any complaint regarding this matter. I will never order from myntra. This is harrasment. How could they keep my money for so long. Rs 1479 is a big amount for me. I want my refund ASAP
