Non-existent customer service from takealot

They sent me the wrong item. I logged a return and asked for them to send me the original product I purchased. I received a return confirmation email saying the amount would be credited to my account. I had already emailed several times and specifically told them I do not want credit, I want what I bought. They have since ignored all attempts at communication. I am sick to death of this kind of *********** customer service. WHY IS IT THE CUSTOMER IS PUNISHED FOR YOUR MISTAKE
