service just keeps getting worst

There was once a time when every single item i needed was purchased from this store, (have a look at my smart shopper account and you will get an idea)<br> a while back i went to the store to buy some basics and the store decided they wanted to close 15 minutes early and the manager completely ignored me, i in tirn just stopped buying from the store unless i really was forced to. On Wednesday, at 18:00 i went to the butchery nxt door and they were closed, so i decided to go into Pick n Pay and get some bread , i ended up buying for the value of R140, when i got to the till and wanted to pay, the machine was faulty, the cashier, fully aware that there is a problem with the system, makes it look like its my fault, speaks extremely rudely at me like i broke the machine, and instead of offering me to pay at another machine she rudely shouts at me that \this machine is not working the whole day"<br> I left my stuff"
