Ordered Projector, received a Microphone

So I ordered a projector on takealot on Monday. The delivery was scheduled for Wednesday and as promised my package arrived early on Wednesday morning. There is just one BIG problem, they sent me the wrong product all together. They sent me a microphone instead of a projector. I am still waiting for them to assess whether or not it's eligible to be replaced. They say that could take up to a week, I actually needed the projector for a presentation this Friday and I was confident that I would have received my projector on time. I guess I was mistaken. I'm very disappointed with takealot and will avoid buying from them in the future if I can find the product in store.
