Pick and Pay online service commits ***** and can't help

I ordered a Hisense side by side fridge on the 25th (order number ***). I got a confirmation email. The order didn't show online, I phoned, they said the order is being processed (26th). The 28th I WhatsApped them, no the order is cancelled, I asked why, they couldn't say why, the branch will phone me ****il now, no contact). I phoned the call centre, it was a mistake the order wasn't cancelled and for a brief moment my order showed online. Phoned 29th to ask when to expect order (as it isn't indicated on their system or online), 5 working days is the reply. Today is 5 working days, I whatsapped again, same consultant clearly states it was delivered on the 26th and it is cancelled again. Their system clearly doesn't work and their consultants are not trained properly as they just say cancel to not deal with clients
