Takealot of my time and money

After being sold a faulty device by takealot I had to return it using a very poorly designed returns system. They then requested that I then had to now pay delivery fee for the new device. After many back and fourth emails they agreed to waiver the fee. Once my new order was finally sent out to me it was a completely different device from the same manufacturer. (instead of a headset they sent a mouse). Now they want me to start this process all over again of returns and evaluations as if it is the consumers problem to make the company send the correct items.
