Disgusting cashier

Received horrible customer service from a cashier by the name of Neo Mmakaipea at Edgars in Woodlands, Pretoria. She was rude, spoke to me in a condescending manner. Also went on to bad mouth her colleague (who helped me with a lay-buy previously) to another colleague in front of customers. My partner brought other stuff for us to buy there, but the service was unbearable so I said we’ll go buy at another Edgars. I just wanted to pay for the lay-buy and leave the store. What annoyed me is I was very nice to her but she just had to be a mean.
