HDFC Bank — Transaction failed but amount debited from my hdfc account

Dear HDFC Team,

I have paid an amount of Rs. 33778/- through HDFC net banking for Myntra Shopping on 08-Nov-2021. First time the transaction was failed but amount was deducted from my HDFC account.
I checked with Myntra and below are the comments from them.

Myntra Comment:
I regret to inform you that your order could not be processed due to a payment gateway issue and unfortunately, the money debited from your account towards payment of this order has also not been received by us.
Further, the same should have already been reversed by the payment gateway. Please get in touch with your bank for further assistance.

Kindly process my refund of Rs. 33778/- as soon as possible.

Let me know if you need any further detail.

Regards
Priyanka k
