Awaiting flight refund due to sickness from 2014

I have been trying to get my refund for over aear now, with constant excuses or broken promises to get back to me every time I contact the call centre.<br> <br> In July 2014 my wife and I had booked our return flights from Cape Town to Durban on kulula. Prior to the trip, my wife fell ill and could not fly. I immediately called the call centre and was advised by a certain agent that both our tickets would be refunded after producing a medical certificate. This was emailed through immediately. Said Agent advised that it would take 6-8 weeks for the refund to be paid.<br> <br> After not receiving any communication for 2 weeks, emails were sent and calls made to the call centre to at least get some confirmation that the refund will be made. We were promised a response from two call centre agents...which I am still waiting for. This carried on for a year.<br> <br> A few weeks ago my wife managed to get hold of the original call centre agent who promised to get back with feedback from the refund division. I am still waiting. This is unacceptable. <br> <br> Please can my refund be investigated and processed urgently. I have tried emailing and calling with no luck<br>
