FLYSAFAIR won't refund

Because of the lockdown I must cancel my 2 flights this weekend. They won't refund you - but will give you a voucher to use within 6 months. WHAT IF YOU CAN'T USE IT WITHIN THAT 6 MONTHS. SLY SLY SLY!!!!!!! Typical South African company - *****!!!!!!! Is it maybe GUPTA owned!!!!!!
