Myntra.com — I ordered didn't get placed but amount was already debited from my account

Website: Myntra

I ordered a jeans from Myntra it didn't get placed but amount debited from my account. I'm trying to contact the customer service but nobody is replying...i don't know how to get my order! I tried many times even to cancel the order or to get my refund but nothing worked.. They're not providing me the cancel option for my order so that I can get my refund!!
