Myntra.com — Online ordered and canceled.. no refund

Website: Myntra

I ordered woodland jacket from myntra app on 24th Jan. The amount was deducted from my credit card but the order was not placed. I called their customer care and they said the amount will be refunded in 3 days. But I got no refund even after 10 days. Now they are saying that they have not got the money and you may contact bank.they are harassing me.
