Unwilling to Help and Disgraceful service

We Book a trip a few months ago Rondawel 5sleeper Adults 5 + 1child, , I ask if i can add an extra child age 3years old and pay the the extra cost as explain at prior booking , yesterday when did the indemnity form it was said that we cannot include the child and that we need to change the venue and pay an extra also R2000 i said for 4year old that doesn't take that much space. Its disgraceful that a manager wouldn't accommodate 3year old, as there is a sleeper couch available in the booked rondawel, it was explain that i should take a slanghoek vila to accommodate the 3year old with an additional amount of +- R2000 which is really pathetic.
