Flysafair- not an honestcompany

Very Bad Customer service, I booked a flight from JHB to Cape town on 29/09/2021 and I tried to move my flight but I was told it cannot be done online and I will get a penalty... I agreed to the penalty cost... then the consultant told me you have to come back and do it at the airport while I was on my way to a Business meeting. and told me I have to do it within the hour after flight at airport. the car got a flat tyre on the freeway and when I came there, no one wanted to hear anything and just said rebook. I lost R3990 and this company is the worst to book a flight at.... I feel ****med because in the end its still my money that was taken and I couldn't move my flight.... if this is how they do business id rather pay extra anywhere else than book with them... the website state you can rebook once for free, because of the covid 19 restrictions but not the case.... saw people crying at the airport because of this kind of treatment, where you get told just rebook.... sometimes we have legit reasons... this company is very bad... why is it that you can book online but not move booking online... totally nuts!!!!!!!
