Missing features in Golf?

We bought a new VW Golf Comfortline in September with driver assist and the navigation package. The GPS is totally unacceptable, it is not up to date and the enunciation is terrible. VW Australia is aware of this and said "not our problem", but they are working on a fix. The navigation system has a traffic function module but we were told during the delivery orientation it's not available on this isn't part of the Australian cars. Further in the handbook it shows two types of an electric mirror folding function — we we're later told this is not fitted in locally delivered cars. Why don't sales people highlight these shortcomings or omissions in local examples and let buyers decide if they want to proceed?
