Disgusting customer service/terrible airfryer product

I ordered a Milex ***l airfryer from Milex South Africa on the 22nd November 2022. They took my money very happily and then absolutely nothing happened. I waited a whole week and then tried to contact them, eventually my order on their website said done and collected by courier (fast way) for over three days I checked the tracker and nothing, my husband even asked if I had been ****med. Eventually just over a week later my product arrive. So now it’s already taken over two weeks from order. I set up my whole air fryer and it all seems to work, only to discover that it’s faulty and keeps switching off when the time is meant to keep going. I send them an email on a Sunday and Monday morning I phone them. Can’t get through, so I email again. After emailing and phoning I finally get hold of someone on the Wednesday, and they say apparently their internet was down. Arrange a collection and will send a new product. All of this takes another week or so and finally on the 22 December I received a new machine. Firstly the courier box was damaged, secondly the airfryer box inside and the polystyrene around it was damaged as well. Take the new machine out and the handle is cracked! So I immediately phone them again and tell them enough is enough, I want my money back please collect your machine. It gets collected on the 23rd December, and according to the tracker Milex received and signed for the machine the same day. I hear nothing more and obviously then it’s Christmas and new year so everything is shut down. On January the 3rd I try contact them again (according to their emails they are back at work on the 3rd) I can’t get through on any phone lines or any emails. I try every day till I finally get hold of someone on the 7th of Jan, he says they have just got back on leave, but According to his email it still says the 3rd. He said he’ll start the process and will email me. Hear absolutely nothing so I phone the next day again, he says they try to refund me via pay gate which is how I paid them and it didn’t work so now they need my bank details. But how did he not tell me this yesterday. I immediately sent him my banking details and he said it’ll take between 3-5 days to get the money. I am now sitting on day 5, still no confirmation the payment has even been made, still no money and I am absolutely fuming! The customer service is shocking, the products are terrible and I will make sure no one I know ever buys from Milex!
