Bad service

My niece is currently looking for an apartment to rent in Cape Town. Made contact with an agent about what appears to be the perfect spot, , and had no response. After contacting numerous Rawson numbers she gets told on a WhatsApp” Good afternoon, take note that the agent was away for a few days but will get back to you regarding this place ”. Firstly, How rude can you be? Secondly, this implies he is back, so why still no response? Thirdly, if he’s away why did he list the property? And why not have another agent cover when on leave? People are desperately trying to find accommodation at this time and this is the response? Horrible.
