Myntra.com — refund not initiated even after successful returns

Address: Mumbai City, Maharashtra, 400089

I ordered shoes from myntra (Order id :[protected]-3311203) on 04 june 2019. I returned the product because the product in reality was different than what it was shown on the app. I returned product and asked for a refund. Even after 30 days of filing for a refund i did not receive it. When i call myntra they tell me they have initiated the refund, after confirming it with my bank i come to know that no money has been refunded back. I sent myntra picture of my updated passbook but they tell me the same thing. I never faced this problem with other e-commerce sites. Please help me get my money back.
