Lack of support

Just bought a MediaBox with the Showmax app preinstalled. When we got the MediaBox and connected it to the TV, the app updated. We then linked our DSTv Now account to Showmax and started the app. We can see all content on the app but when trying to search for particular content, we can type into the search bar but there is no search button/option. We have been sitting on the online chat for about 45 min now. We eventually got through to someone but they took a further 15 min to reply and then the chat reconnected. Incredibly frustrated. So sad when you want to support a local business but regretting it at the moment. If anyone can help, that would be great.
