Bad customer service

The Cashiers at Superspar Empire Welkom are so rude I went to soar yesterday to buy and both the cashiers there are so rude they don’t even wear name tags but likely the slip shows the name it’s Mary M from Till 007 and the other cashier I didn’t get her name but in description she is short in height and also has short hair she was working next to Mary M

Please offer customer service training to the cashiers there but as for me am no longer going there
