Myntra.com — Money got deducted and order not placed

I had placed my order on myntra app on 4th November 2020. The amount of INR 2113 was paid successfully through google UPI. The order ID and reference number was also generated. But the app didn't show any such data of order being placed . I called the customer care but they kept stalling me . They asked me to wait for a week or two then they asked me to check with the bank. I checked with my kotak bank but according to them the amount has been successfully credited to the beneficiary's account. They are not ready to return my amount.
