Myntra - Refund not received

Produclct was returned on **th Feb, Myntra said refund had been initiated. When i did not receive refund after ** days, i called thier customer service, they told there is an error in the refund and refund is showing failed at thier end. They said they will raise a complaint and i will receive the amount. After more than ** days, i did not receive any refund. I checked again with thier customer service they told me there had been an error in the refund and that they are raising a complaint again. I did not receive the refund. I checked again with their team, this time they told me at all the executives have been giving me wrong information, refund was processed successfully from thier end and i should follow with Bank. Its been almost a month and i have not received any refund. Myntra team has been providing me wring information and now they are saying sorry for the wrong information but we cannot do anything.
