[Resolved]  PayU — Money debited from my Account order not placed with Big Banyan

I was placing an order on Big Banyan Vneyard India online on 30th July and had opted for payment via upi.
I then did the payment through PaytM for which Big B anyan had used PayU payment gateway. The transaction amount is Rs. 3, 540
I did the transaction via CitiBank and money got debited from my account but Big Banyan did not received the amount. Big Banyan has shared a screenshot of their receivable page stating the money is not reflecting at their end and Citibank has given me a written confirmation stating it's a successful transaction from my bank account.
Please arrange to refund the amount asap.
