Refund due to COVID19

Currently on hold for the past 18 minutes, this is also more of a need to know post, as i am travelling on 23.03.2020 with a return flight for 27.03.2020, for non essential travel and following President Ramaphosa's speech yesterday declaring the country currently in a national disaster, I would like to know if a refund will now be awarded due to the fact that we can not postpone dates as we as with the rest of the world are unawares of what is currently happening and when the COVID19 will allow for travel again as it is a Global Pandemic... should the airline not refund us as it is not due to any negligence or fault of our own and we are unable to change the dates as the future dates are uncertain
