WORST COURIER EXPERIENCE EVER!!!

So I ordered something from Makro about 2 weeks ago, it was supposed to be delivered on Friday the 13th of December. It wasn't delivered on the Friday. I tried phoning them. No answer. Saturday comes and I receive a notification that my order has been delivered. I thought to myself, okay fine there was a delay, they just maybe forgot to inform me, that happens. I phone my mother in law that is at home and asked her if she signed for the delivery? She asked what delivery? I then asked the courier guy? It says that my order was delivered. She states that nothing was delivered. So i then again tried phoning and emailing and all that you can think of to get in touch, but yet again no answer. And this was within their operating hours. The whole day nothing. I tried again and again and nothing. They keep on insisting now that the item was delivered, making me out as if im lying. I want to know where my item whas delivered? I want to see who signed for it as it is not in my possession. If I do not receive my parcel or a full refund by Thursday the 19th of December 2024, I WILL take this further. I will get in touch with the Consumer Goods and Services Ombud in South Africa. Your customer care and customer service is the worst. My next stop for a lovely review is Google.
