Excellence customer service turned into arrogance and rudeness

I went to clicks Gezina galleries on the 24 June for exchange of their branded pads to a big size but their same brand. Ive ask for assistance then call an assistant manager Avele to come assist. I went to the till greet the cashier Nthabiseng she kept quiet and u could see she is putting on an arrogant and rude face. During the exchange she decided to stay outside the check out area, far from her till. She left me and the assistant manager to process everything without her presence. When asked to come back to process payment. She continued frowning and looking at me in the bad way. Never to ask for plastic or anything even when I wanted to ask her something. She put my change on the desk and left me on her till to pick my things. I'm so much disappointed in clicks staff so much arrogance. The cashier doesn't respect or serve customers to fulfill the company values and mission. She is full of herself and make me look like doing an exchange is troubling them. This kind of service is chasing customers away and the cashier should get corrective counseling to make them remember why they choose to serve customers.
