Cancellation refund

I made a booking for my family in March 2015 and paid in full for my flights in August 2015. I had to cancel the flights die to my father's falling ill on 28 August. They offered me a cancellation rebate of R234 per ticket although I had a medical reason for not flying. My father passed away on 26 September and I haven't received the rebate at all. I am very dissatisfied with the amount they are offering me and that I have to wait \6 to 8 weeks to process"it.<br> <br> This is not fair and they have no consideration for your position or situation"""
