No delivery, no refund, total silence

Order placed beginning of May 2023, still not received. I have emailed the Support Centre which responds now and again. At first it was delays because order had to be fulfilled from overseas because of demand, then the courier company, ad then I'll follow up and get back to you. My final request was for a refund which had to routed to higher up, and when I request an update there's silence. Shocking service.
