Rude cashier

one of your stores in Littlesfalls (Welgehuewel) and the lady by the Name of Nobuhle( cashier) rudely told me they were closed she won’t help me because she was already cashing out, I don’t mind them being closed but if you are closed why keep your door wide open? Please do better. She even said oooh I will call the manager for you, mind you the door was wide open at 20:05, you customers service is so poor, you need to take your caishier to customer service training
