Over 5 months & Kulula has not processed refund

On 3 September 2015 Robin Williams from Kulula informed me that Kulula would cancel and refund my 2 return tickets to Port Elizabeth on account of the serious medical condition of my dad that we needed to attend to.<br> <br> I submitted the requested medical certificates from the doctor and hospital confirming my dad was in ICU with a neuro disorder.<br> <br> There have been numerous emails between Robin and me over the last 5 months; she keeps promising that it will be sorted out and apologizing for the delay.<br> <br> Yet the refund has still not been processed.<br> <br> What's going on?
