Items not delivered

On 26 November 2024 I ordered items worth R28 000 online for delivery. I received 3 of my 4 items ordered. The contact numbers provided do not exist, they do not respond to e-mails. I would like to know where my Dishwasher is that I ordered and paid for. It's now the 4th of December and still not a word from anyone. They just ignore you. I'm not freaking happy at all. I will most definitely not order anything from them online ever again. Very bad service.
