Beyoung — Payment not received

Sir, I had placed an online order through Beyoung consisting of 2 cargo joggers on 16.10.2023 at 08:26 AM.
Even mail regarding successful payment came but the order summary doesn’t reflect the same. Moreover same items are there in my cart and app prompts me to complete the payment.
The same issue was raised to seller and they denied of getting any such order. I have confirmed with bank that the payment is successful.
Now for past one week I have been informed that my money will be sent back but there is no action yet.
