FlySafair Covid misery

In November 2020 my daughter and I flew to Cape Town for a funeral. We were to fly back to East London on the 18 of November but on 17 November I tested positive for Covid, I immediately contacted the airline to inform them and spoke to and emailed a FlySafair consultant by the name B Moepeng explaining that I could no longer fly on the 18th November. I sent in my Covid test results and heard nothing in response. I had then contacted customer care and the Covid helpline and forwarded them an email and to date have heard nothing. When I booked my flight I even opted to pay all extra insurances for eventualities. As a a frequent flyer on this carrier, myself and my extended family, I am disgusted by how my problem has been handled and by the lack of response from this airline.
