Bad customer service

I went to Totalsports Sandton City on the 24/01/2022 just around 11h30. I requested a refund and the teller by the name Wendie told me that she cannot assist me because there is no cash in her till and that I have to wait until someone else comes back from lunch at 12h30. The attitude she gave me was gruesome. She even went as far as opening her till and removing the cash drawer. How is it that it's the customers problem that tellers do not have cash in till? So what happens if I make a cash purchase and require change? I was literally told to go and come back after 12h30..

I am unhappy about this service because it is the very first time I get such from a TFG store and I must say I am shocked.. I have a Totalsports account which I have had for 8 years and never ever have I received such ****ty behavior from a sales person
