lack of management skills and very bad attitude

I went to Spar Tops apparently the fridges were not working and when we asked for cold drinks, first of all the cashier with attitude tells us you 'know where to get them' with the manager standing next to her. we then asked the manager in English which I assume is the business language. manager then rep**** in Zulu saying (ngizokusiza kanjani ungakhulumi) how do I help you when you not talking. I then asked him, what do you mean coz we've been asking and no one is willing to help. he didn't know the guy that was asking was my husband which he didn't even understand why I was getting upset. the problem with him is that he was getting upset because I was now translating what he was saying in Zulu to English. that's when he asked me what does all this have to do with me.he told us to go pay elsewhere. we then left. my problem here is I buy from this spar everyday because its very close and convenient for me. but with this attitude and service we receive I think as the customers we deserve better. this Lawrence guy better change his attitude and stop treating customers as if they are his friends. hopefully my complaint will be taken seriously.
