Takealot Services and Policies

The wrong item was chosen and items was already paid for. Once the mistake was noticed, I phone the customer service number to ask if they would be able to replace the incorrect item with the correct item and I would pay in the difference immediately, because they have a no return policy on their masks. I was then told the company could not assist me as they have no such policies to assist their clients. So I asked the employee of takealot so I just have to except the incorrect product and there is no way to swop/return it and the answer was yes. I am so utterly mad, because the company *****s their clients over, because now I have to accept an item I do not want/ed. They deliver a service and what is service about, pleasing the customer.
