Cancelled flight - No communication

What a clown-show. I arrive at the OR Tambo airport for my 07:10 flight (MN601) on 2 March 2022, only to find that my flight has been cancelled and no-one seems to know what to do. And no communication.

Kulula can spam you with marketing material, but seems unable to inform me that my flight has been cancelled.

Rather choose another airline as Kulula seems to be racing SAA to the bottom.
