Myntra.com — Double transaction through g. pay to myntra.com

Sir,
I had placed an order for one vishudh flat and 1 Anouk mule on myntra.com on 12 june 2022 at 19 :15.Unfortunately the transaction said payment failed, so i paid it again, the amount of Rs 700 was deducted twice from my J&K Bank account . Also no trace of the double transaction can be seen in the "my orders' menu as well. Kindly force them to refund the amount debited from my account.
Faithfully,
