Unfulfilled order, no response from support.

I ordered and paid for a lawnmower on Tuesday 29 October, and specifically chose one that showed as in stock in jhb. It said it would be delivered by Fri 1 Nov. By Thursday evening I saw it had not been shipped yet and sent an email to enquire. I got a reply asking me for my details, which I sent literally 1 minute later. Friday came and went, no delivery, no email response. I sent another email, no response. I created a new support ticket, no response. It is now 1 week after I've paid and the lawnmower still shows Deliver by Fri 1 Nov and has still not been shipped and still no response to my support ticket. So I'm just being ignored basically.
