BAD SERVICE

I ordered a product and the wrong product was delivered. I logged a return and they collected it and delivered a new product. BUT they delivered the same incorrect product AGAIN. How do they get it wrong twice?? Clearly no one checks these orders!!! Its been 2 weeks now. I get told (via e-mail) it is being followed up with the warehouse but that was days ago and I have heard nothing. I cant even find a telephone number to call!! I spend a lot with Takealot but this is just such bad service!!!!
