Myntra.com — Amount debited twice and money note refunded.

I ordered from Myntra.com on 6th August 2021 and when i was at payment gateway,
The payment failed in first attempt then in Second attempt it.was successfull.

But the amount was debited twice from my account and I haven't got my refund till now.

I mailed myntra and also tried to reach them in other ways but I'm not getting any response.

Below are the two debit receipt i recieved at same time for just 1 payment.
