Time to change my online shopping provider

I've ordered a set of blinds for a room that I was redoing at the beginning of October 2023. Four months later the room only has one blind up and the other window uncovered as Takealot can't seem to get the simplest of orders correct. Four times the wrong colour was delivered and the other two times they cancelled the order because the supplier was out of stock. How difficult is it to look at a blind to select the correct colour before dispatching it? What's worse is, when the blind was out of stock, Takealot has no issue throwing the supplier under the bus; this of course only when I call in as Takealot can't be bothered to communicate properly. Utterly disgusted in this shocking service and so frustrated that Takealot doesn't care how they've inconvenienced me!
