Complete Lack of Communication

I ordered and paid for a toaster from Loot on 14 May 2020. On the confirmation: "Latest expected shipping date: 26 May 2020."

On 29 May 2020 I get this email: "Unfortunately, there has been a delay in receiving "Delonghi Scultura 4 Slice Toaster (Bronze Beige)", which we expect to receive from our supplier on or around 9 June. Based on this information, we expect to be able to ship your order on or around 10 June."

On 10 June 2020 I email them and ask if the delivery is stall on schedule, besides an automated reply, no answer still and today is 18 June 2020.

I phoned them last week on 12 June 2020 and they not answering due to Covid-19 but will reply to my email within 72 hours. So I go register myself a Twitter account so I can Tweet them. They have ignored my emails, Tweets and phone calls.

What am I supposed to do? I understand the world is under pressure at the moment with service delivery but communication is non negotiable. Staff can work from home and therefore 100% capacity on communication can still be possible. This is really nonsense. I will never again use this company for anything, even if they have a good special.
