Unhappy and annoyed customer

Long ques and the staff are rude to the customers. I was in a line for laybye out, I got moved from the main line to the line for payments and laybye. Only to b told that I can't cancel or exchange a laybye when it's my turn to be helped. I had to move to the line that I was on again both cashiers were rude and on my case. Nonku and Kele and that time I'm 6 months pregnant. While on the line system goes offline they didn't care to tell us what's going on. The service of this store is ****.
