Staff can't use till system

I was disappointed when I went to purchase a few items at foschini with my gift cards to be assisted by someone who does not know how the gift card system works. Please train your employees on how to use your systems because it creates a bad name for the company if the till lady tells a client that your system can't perform a certain function but yet she is the one who can't use it properly. <br> <br> Could you also improve on tills that shows the customer the amount when items are being scanned. Because it also annoyed me that when this sales lady was done scanning my things that she just wanted payment without telling me how much am I paying for. Thank you.
