FlySafair ignores the consumer protection act

I had to cancel my bookings due to unforeseen circumstances. Flysafair issued me with a voucher without giving me the opportunity to request a refund into my account. This is apparently according to their policy. If I unable to use that voucher within the specified time, I will forfeit that voucher and lose my money. How legitimate is that in accordance with the consumer protection act? Am I the only South-African that ever complained about it? This is nothing other ***** on the side of FlySafair. I expect to be refunded into the account from where I have paid it.
