Myntra.com — money debited order not placed

I ordered 2 jeans from myntra on 12 may 2018. The money got debited but the order wasnt placed i checked my bank app and the statement shows its debited. When i checked myntra it shows order is not placed. So i called the customer care he told me something and he told within 48hrs ill get my cash back. I have no idea what is going on please give my cash back.
