Kulula.com a big ****,i want my money back

I have booked their flight for 2 my self and my husband on the 9th of March for the departure of 12th march 2022. Then i decided to change my flight on the 11th to be for the 13th. Something came up again then decided to change and i went straight to airport and met the consultant ,she then changed and re-book by 15h00 or so for me for tjw 14th and told i have some change. Boom in the evening i received a message telling me that the flight has been suspended,and i will be rebooked another flight. When i went to airport to check which fligjlht have they booked for me. And there were no one on the teller and even closed. No one to answer my question,or to give directions,their lines were off too. Now my concern is that,why did they booked me their flight again,knowing very well tjhat they are suspended already. I spent money to go to the airport,i waited for them to book me another flight as they promised. I had to book a bus because there were no flights available. I had to pay another for uber to take me from Airport tp bus station,i have paid around about R600 for uber. I dont even wanna mention the trauma of travelling for 29hrs with a bus to reach Cape town. The condition,the price of the bus for my desparation. KULULQ.COM OWES ME UP T0 R5000 AND I NEED IT IN CASH AS I WILL NEVER AGAIN USE THEIR FLIGHTS,I WILL NEVER TRUST THEM FOR THEIR POOR SERVICE,because they should havent book a flight for me on the crisis they aware about. And i dont need to be paid by given a credit voucher by them the money is mine not theirs if i can bee short witj even R10 on their flight fair. I NEED MY MONEY BACK OF THE SUM OF 5000
