Shocking Communication on Flight Changes!

Currently waiting at OR Tambo 07.11.21. Flight was originally booked for 17h40 departure only to be changed (WITH NO COMMUNICATION VIA PHONE CALL, EMAIL OR SMS!) Staff at the Flysafair Counter were EXTREMELY unhelpful in explaining why? When I asked the question as to why my flight was changed with no communication I was told to contact Flysafair directly to complain… Clearly this is just an income for them with no intention of actually helping their customers… Passing the buck is just way easier! Honestly so disappointing that major airlines within South Africa get away with treating their customers badly! This is the last time I use this airline… Its a pity as there are hardly any good airlines left in SA that truly care about customers service! 3rd World Country Problems.
