Extremly bad service

I tried to pay with my rewards card(Ucount) as it is acceptable at Clicks stores , and the Cashier (Andiswa) asked me whether it was Cheque or Savings , i responded , its a rewards card, so its neither cheque or savings, she responded ma'am, i cant help you if i don't know what type off card this is,she looked me straight in my face with an attitude_she looked very irritated, she didn't even attempted to swipe the card and was just staring at me, her colleague, advised her to try savings and the transaction went through, i asked to speak to the manager, and she came, all she said was i will deal with this, and i left.<br> i went back the same day to get something else and was assisted by the same Andiswa, no greeting,no thank you, just \your clicks card please"And this time her manager was standing in the back ground"
