Bad service and attitude Edgar's mamelodi denlyn

I was at Edgar's mamelodi denlyn and got the most horrible service . I went to do refund and the cashier well like we don't have money and asking one another for the R300 and they said you can go and do window shopping in other shops until later maybe you will find you 300 with some bad attitude so I just got irritated and left .with such attitude towards customers I am not surprised when most Edgar's shops are closing please train your employees customer service
