Shame on you - I am human

I booked a flight on 11 January for the long weekend in March. Unfortunately i fell and broke my foot on 23rd Feb and because of both personal limitations and the medical policy/ assisted boarding policy for FlySafair, I made the decision not to travel. FlySafair failed to take the time to understand my personal situation and are so hung up on their cancellation policies, that they were only prepared to offer me a 50% voucher to be redeemed against a flight in the future. What do I do? i took the 50% voucher as I suppose it is better than nothing. If they considered giving me a 100% voucher, I would need to be in hospital on the day of the flight and prove it. The reality is that my seat will be filled easily and they will make probably double what I paid. Shame on you FlySafair. You have taken money from me that you did not earn, Shocking!!!!
