Wrong Product delivered

I ordered a pair of Ray-Ban sunglasses and instead was delivered wireless earphones (worth approximately R2000 less). Unfortunately Takealot does not have a customer care line, you cannot request anyone to call you either to discuss the process. Instead they will collect the item, take a few days to determine in was incorrect and then a few days to deliver a new one (if they still have it stock), by then I will be on holiday and the whole purpose of buying the item is for the holiday. The product is no longer in stock yet i get credited the discounted amount. I could have bought the item on special (black friday) from other suppliers but missed out on their discount and now will no longer be able to afford the product at normal prices.
