BAD SERVICE BAD ATTITUDE

on the 4th on November i visited the Edgar's active at Tsakane mall , there was a long Queue , there was 1 person working at the till , after standing in 1 spot for 15-20 mins i figured let me get the store manager to enquirer about why there was only 1 person . he 1st told me he was busy with the another customer which is understandable , before he was done with the customer he asked me whats the problem , i asked him why are we having 1 person working at the till , he said if there is no Queue at the cellphone till i can go there ,so i went there peacefully , he than followed me to the till saying no the lady was busy doing cellphone activation so it might take a while , i said OK so Why are we there 3 people at the cellphone till are they all activating 1 cellphone, can he split the people to the other till to balance both the tills , i shouldn't have asked that question because that is when he gave me attitude by saying if i can not understand then there is nothing he can do plus his busy with a customer, he went on saying the people at the cellphone till do not do the same job, 1 guys was from Nokia , i asked so this mean he will not open there other till( i was saying this in English ), he said i must stop speaking in English i should not act white and speak Zulu which i repeated the same sentence in Zulu,(so does it mean i am not welcomed to speak the language i feel more comfortable in? , just be because i am black does it mean i am Zulu ?) as i am saying this he was walking away , so i am offended because he was shouting and he still didn't resolve anything because the queue continued with 1 till open until i left .
