Myntra.com — amount debited from my account but the order hasn't been placed

I have an placed an order on 4 july 2019 on myntra of ₹4201, amount deducted but order hasn't been placed. So i have contacted their customer care but the customer executive claims that they didn't received. But after contacting my bank they confirms that the amount has been transferred to myntra pvt ltd and also the bank employee said that as the amount has not been bounce back to me so definitely the amount has to be received by myntra only. How can myntra cheat like this. I want my money back asap or else i have no any other option left rather than filing a case against myntra.
