I am extremely disappointed by the service I just received at kokstad mall branch clothing junction... I was just in the store buying 3 Tshrts that are promotion for R120 and the cashier Moipone rudely dismissed me when one of the Tshrts did not ring up as promotion... And I asked can't she call her manager to over write as the Tshrt is lighted under the promotion items? She then told me no if I want to complain I can go ahead but she won't change it. And she called the next customer while I was standing there.
