Refund my money

I am frankly appalled. Whilst Cemair are to be held responsible for so many passengers having to make alternative arrangements, such as my booking in December, Kulula should be in a much better place than Cemair to refund. They are not suffering the same cash flow crisis as Cemair. But alas, my refund claim registered on 26 December, more than 8 weeks ago is still "in process" and I will get a call from the refund team. I enquired when I would receive the call and was told probably today. I have been on the phone listening to the same message for about 35 minutes and no conclusion. It should be ******* for them to 'play with passenger's monies as though in a game of monopoly'. It is more than R5,000 they owe and they are certainly not going to garner any loyalty from me as a passenger. Off to Safair I guess. Which body takes up this issues? Civil Aviation Authority?
