Bad service from SAA

Not impressed with South African airways at all, our flight from Durban to PE was delayed by 6 hours initially with nobody notifying passengers via sms or email, then a further 3 hour delay with no notification to passengers. We eventually flew the next day from DURBAN - JHB and then Jhb - PE, although we went to board our flight to Pe in Jhb, only to find the gate had been changed yet no gate number on the screen. So after missing our flight as we Did not know where to board, we explained the situation to the staff who didn’t seem to care and charged us an extra R2000 to get on the next flight. What was supposed to be a one hour flight home landed taking us 24 hours to get home and cost us an extra R2000. Extremely disappointed with the service and will never fly SAA again.
