Burger King India Private Limited - Payment done but order was not placed Refund was not processed

This has reference to the subject matter, on **/**/****, me and my friends had visited BURGER KING STORE at PVP SQUARE MALL, *RD FLOOR, VIJAYAWADA. Even though we had visited the store for In-Dine, we had been asked to order online through QR Scan they provided.
I had ordered for Rs.****.** with the order details as per attachment under order number #****. But the subject order was not reflected in their pending order list. So we had been asked to wait for some time, meanwhile they had started to prepare the order items which we said.
As it took more time, they asked us to order again offline and they told us that the online payment will be refunded within * to * days.
Further the subject order has still been in PENDING status
Even after a month I am not getting any response from your side. I am very much fed up with your customer service. I had visited the store thrice, even though there is no proper response. They simply sending mails and ask me to wait.

Worst service I had received ever. Look into the matter and do the needful.

I had attached the screenshot of the same.
In this regard, I am escalating the subject matter to your perusal believing I will get proper response from your end.

The Order Details are as follows

Order No: ****
Date: **/**/****
Name: ASWIN KUMAR
Mobile No: ***** *****
