Myntra.com — refund not credited in my account

Website: Www.Myntra.com

According to myntra, they had initiated the refund of rs1427but it had not been credit to acccount. According to my bank it's the myntra who had not sent money and myntra is blaming bank for this. Reference number given by myntra[protected] which is of no use according to bank. I have been calling myntra many times but their response is same that they have initiated the trasaction and they can't do anything. On asking the solution they asked to contact bank and bank is asking to contact myntra.
Myntra is a fraud website who is just wasting my time and money.
