Airlink airways bad customer support and treatment of customers

Bought a ticket for someone else which i cancelled due to unforeseen circumstances which occurred. Cancellation request over a month ahead of flight . Unlike Flysafair, they do not issue vouchers. To prevent a financial loss , they offer to rebook at the following financial loss . Rebooking fee of around R600 and change of passenger of R650 , rendering this a total loss of an airticket- not customer friendly at all like their competitors like fly safair and link
