Poor service when refunding at Game Fourways

I am so dissatisfied with the service at Fourways mall for the 2nd time. This time my issue is with Simangele Masondo who wouldn’t refund me bcoz she had cashed up yet there were customers in the store. She was rude in her approach then she continued to tell me how it is late and I should’ve told the security guard that I’ll be refunding, of which my answer was that it is not written on the entrance or the till slip that you need to declareJust refunds at the entrance. She finally figured out a way to refund me but she just handed me a voucher, I told her that I did not want a voucher then she continued again and told me that I should’ve told her that I want cash. Is it not her responsibility to provide me with the refund options so that I may choose. She instructed the cashier to give me cash and she walked away without saying anything. Game has to invest in customer service training for their POS staff, supervisors and managers because the floor staff are great and always willing to help
