Flight Cancellation

So a couple of months i purchased a ticket with Kulula to cape town total return flight R1300. unfortunately my trip had to be cancelled because of work circumstances with my husband. i called kulula and explained the situation and they said they wont pay me a cent back for cancelling. i asked what about the taxes and charges, and they said \it wont be that much"(obviously to them because they are keeping the rest of it). i was then advised that i should have taken a refundable ticket (note there are no refundable tickets mentioned online where most people buy their tickets and you can only get them if you call in) but the website makes no mention of this. so how do you know the option is available? either way i need to cancel to the trip so they said they will send it to the refund department and i will be advised between 6 to 8 WEEKS. For a company that prides themselves as being the number 1 local carrier with a #madeeasy tagline. yah right. thank you nothing"""
