Myntra.com — regarding order not placed and money got deducted

Dear Sir /madam
I placed an order on August 12, 2019 on myntra of INR.2698.5, amount deducted from my OBC account but myntra claims that they did not receive even though my bank OBC confirms that amount has been transferred to their account but they are not accepting that amount is transferred and continuously asking me to contact my bank.. what is going on.. how can myntra cheat like this. they are not accepting due lack of will to transfer back the money. i want my money back.
