Kulula - Shocking experience

I had a flight booked from JHB-DBN tomorrow flight TYHUYV. I receive no email notification besides a non formal phone call stating that my flight has been cancelled for flight TYHUYV. Phone number used was (011) 393 - 7600 ( Comair ops ) which called in at 7:45pm stating they will call back at 9:00pm to give me a new booking. It's currently 8:51pm Thursday evening the 17th December 2020 and have not received any further communication. Its upsetting that the system is not integrated with the customer care ops team. I have tried to call Kulula customer care and the number that contacted me and no response from either which is unacceptable. I have an early appointment booked in DBN and now has left me to book with Fly Safair at another additional cost which i may claim for as well from Kulua to compensate the matter. I can not afford to go to the airport tomorrow hoping to get assisted onto another flight therefore i have booked with a more reliable brand Fly Safair.

I request a full refund due to the unprofessionalism from Kuala and for messing me around with not assuring me with any guarantee and to compensate my new fee of R1,548.00 for Fly Safair and Kulula of R2,992.00. So in total the amount will equal R4540.00.

If this matter is not resolved within the next 24 hours - I shall proceed with legal actions against Kulula.

I attached two recipients as POP for Kulula. A month later still no response? Disgusted to understand how a reputable brand should we say - cant assist the matter with no communication & no customer service and the list can go on and on.
