Unhappy customer

I bought 22 items which were over R4000 My estimated delivery time was 5 days, it’s now been almost 3 weeks, they say it’s because one of their items wasn’t in stock, why would you let me pay for something that isn’t in stock. Now I emailed them to send the 21 items that are available and the one item when available and they want ME to pay the delivery fee for the second time. It’s now day 3 of waiting for takealot to email me back. I’ve been a loyal customer to them for a very long time now and I’m extremely unhappy with their service. I ordered on the 8th of October and my estimated delivery is now the 28th of October. This is utterly unacceptable!
