I have ordered kurtis from myntra on 12/07/2019 and paid the amount of 2024 online. But then after i cancelled one of the kurti amount 624 on the same day.
Myntra sended me email that amount has been initiated, but i didn't recieve it. When i called customer care they told me to wait till 22/07/2019 amount will be credited. But when i called the customer care on 22/07/2019 they told me to contact bank. Now i am unable to get my refund.
