Wrong product delivered, no customer service available

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. It is ridiculous you are not even given the opportunity to voice this with Takealot but are forced into their impersonal, tedious and time consuming process despite it being their mistake.
