Managing children's zip cards is extremely painful. The site varies from being just about usable with the poorest UX I have experienced to being completely unusable.In the last 8 months of having to top up zip cards, I can't recall a single time that it just worked. Normally the payment page doesn't work and I have to use different browsers on different devices until it finally allows me to make a payment. A lot of the time you can't even log in, when this happens I give it a couple of days and try again.Finding how to complain about it is also very difficult, I guess most people don't bother.
