Sanparks booking system frustration!

Calling the Sanparks telephonic booking number is utterly frustrating! One has to hold on for VERY LONG periods! As example, on 21 and 22 and 23 January this year I spent a total of 3.5 hours listening to the digital voice message telling me "you are currently number 27 in the queue...." An hour later you hear "you are currently number 13 in the queue..." It is heart breaking! It seems there is only one person operating the call lines! The alternative of using the online booking system is equally frustrating with frequent gremlins and an non-user-friendly interface that sometimes lacks basic user logic. It is such a shame. We can make so much money from our National Parks (that are excellent) if our booking service is just better run!
