Myntra.com — not got the refund

I ordered adidas running shoes from myntra on 18th feb. I issued request for return on the very same day. Next day my return was successfully done but from here the struggle began. It's been 2 months now that i am waiting for my refund. Everytime i call the customer care they tell me to wait for 24- 48 hours. But it's been 2 months and i've not recieved my refund of rupees 2149. They told me that my bank account details were wrong then i gave them another bank account details but everything came to be useless. I called them for whole 1 month regularly.
