Myntra.com — no refund money

I bought ms. Taken jogger. Because of size issue i returned this product. And waiting for my refund. They asked my bank details 5 to 6 times. Each time i mail my bank details through their contact us service. One time they said that your request is recieved and refund is processed (5/12/2017). On the next day (6/12/2017) they said they haven't received response so they close my case. After that i call customer care number they said their is no refund left. I check my bank transaction but haven't received my refund of rs 996.97 yet. It about 3 month but i didn't receive it.
It really disappointing.
