Tidee.co.za - New South African Company

I ordered two Tidee airfryers at the beginning of October and after back-and-forth emails was informed that delivery would take between 30 and 45 days. Still waiting... They continue to advertise, encouraging more and more consumers to order and then not delivering. There are some reviews where people appear to have received their airfryers so I wonder if this is a pyramid scheme where they may receive 100 payments for orders but then only make good on ten for example. This is so disappointing as I had intended to gift these airfryers but it doesn't look as if I will be receiving them anytime soon.
