Nonna's Italian Kitchen Umhlanga food order not recieved

I ordered food for takeaway directly from the Nonna's Italian Kitchen Umhlanga website, paid with my credit. I received confirmation of order and reference number via email and text. It turned out though the restaurant was closed!! They were closed but the food ordering system on their website was still active. I paid a total of R859 with my card and have no way of asking for a refund as the only number available on the website is the restaurant land line and the restaurant is closed!

My order reference is 98492
