Refund my money

Flysafair sent me a message on the 16th of December notifying me that my return flight has been cancelled. This was on the evening of the level 3 announcement of lockdown. I have sent proof of my flight bookings with the itenary. They inform me that the message was sent in error yet when I called their contact center my return flight had indeed been cancelled. Today they are telling me that the message was sent in error and they refuse to refund me. This has been the worst experience thus far! Asanda
