Poor customer service, false advertising and no refund

Absolutely shocked that such a large supposedly reputable retailer can neglect service. Ordered a fridge online during their Black Friday special. Fridge was paid for a week later, still received a message that delivery was taking place. On my way driving to Durban where it was to be delivered I received an email that they’re out of stock and will refund me. Tried to escalate the matter as we then had no fridge while on holiday but to date received no feedback. Surely you promise something you have to deliver not tell me it’s sold out and you will simply refund me. I wonder if anyone from Pick n a pay will even bother to respond. The right thing to do is get another fridge or assist in some way because it’s not my fault you ran out don’t falsely advertise. Never shopping there again I’m surprised with the amount of complaints on this forum that they still have customers!! They probably gave my fridge to someone else and **** there’s no stock.
