Unprofessional and Rude

Courier behaved unprofessional and obnoxious during delivery. I would like to cancel all orders that I am still awaiting - this behaviour is unacceptable. Unfortunately the gentleman wouldn't give me his name or details. What is the point of ordering online if couriers behave like bellwether of rude cashiers? Would you please see to this matter. I do not want a Takealot courier near my premises untill this debacle is resolved. Regards Pieter Stemmet
