Takealot service degrading

I have tried unsuccesfully to find an email address for complaints at Takealot so I’m posting here. I recently ordered 4 Mihome temperature/humidity sensors. They sent me two and a dog bowl. I returned the dog bowl after explaining at length to the supervisor (Adam) what the problem was. They sent me one more sensor. I just got off the phone with takealot asking them (Baby) for the fourth sensor. I have always had excelkent service from Takealot but this happening twice in a row on the same order is concerning.
