Poor customer service

On Sunday 25/09/2022, I went to Akermans at Umphakati mall. There was 1 cashier working, she kept calling someone to come help her. Eventually I was next, I got to the till and asked if I could pay my layby and take it out. According to the cashier, layby's were offline yet I could pay my layby but couldn't take it out. I'm still confused, if the layby's were offline how could I only pay? Nevertheless I paid and left. It's absurd and frustrating that there was no notice anywhere in the shop indicating that they're offline for layby's, but you can pay...
