Absolutely shocking customer service from kulula

I received an sms this morning on the day of my flight stating that my flight has been delayed by about 2 hours. This makes the flight worthless to me as a have to attend a meeting tonight in Pretoria east at 7.00. I have just spent more than an hour and over a hundred rand on airtime trying to rectify this. I requested that the consultant call me back if the call disconnects but the consultant said the system is not able to(nonsense, you have my cell number). The call did in fact disconnect while I was waiting for the consultant to speak to the supervisor. Now I have spent about R2000 on a flight that will not get me to where I am going on time. I had called just a few days prior to adjust my flight time to something more suitable and had to pay in an additional R1300 to do this. Now I have spent the R1300 and you guys have changed the flight to an unsuitable time! Additionally, I am still owed flights from kulula for a flight that was booked in march lockdown which I obviously would not have been able to utilise and which I now hear is only usable in the next 6 months. Which makes those flights worthless to me as well . Thanks for nothing kulula, I will never use you again and will tell everyone the same
