No refund for 2 months?!

A booking was made on 29/04/2015 through 3rd party for departure on 26/12/2015 with Kulula. At the time of the booking I was pregnant with my 2nd child.PLEASE CHECK THE ORIGINAL COMPLAINT FOR FURTHER DETAILS HERE. Words fail me having to recall the service received by this individual. She said our flight was upgraded by Travelstart in September and we now need to pay a further R3851.80. Finally at 6:35 we check in. We are then asked to take our luggage to the flight and proceed to the side security. Keeping in mind I have a 4 month old and a 6 year old, 3 suitcases, 2 carry on's, a car seat and a pram. My 6 year old having to manage and run with the pram down the ramp to the airplane. I am stressed beyond belief, R4k poorer, a 6 year old that's scared out of his mind and a fussy 4 month old. 30/12/2015 I log the complaint. 04/01/2016 David Holland (Comair Cust Rel) emails me back and say you can do credit (as gesture of goodwill?!). I say no, I want my money refunded. To this I'm told it must be investigated first. I receive confirmation that it was indeed Kulula's mistake and I will be refunded within a week or two. That was a MONTH ago.Emailed David on 24/02/2016, no feedback yet
