Myntra.com — payment received but order not placed

Address:

Dehradun, Uttarakhand

I ordered a roadster black t-shirt from myntra on september 29, 2019 around 8:31pm. The payment was made through paypal, i had a 400rs discount voucher so the order total came down to 123rs. The payment was made and amount was deducted from bank account.
I called myntra customer care service, they said the payment was made they didn't receive the payment on there end because of gateway issues.
What should i do, cause the payment is deducted..
