CemAir disappointing airline - they should shut down

Firstly we almost never took off on our flight as the “electronics were shorted” and the plane had to be manually be “kickstarted” before we took off (first experience with CemAir)

Booking our George flights from Johannesburg we were told only certain flights available. Due to health restrictions we were forced to postpone our flights and trying to book them again we were told that an additional charge of R1500 pp was going to be charged (above the R5500 we already paid) for the new flights (as the old flights were no longer available). This amounts to a total of R8500 for 2 passengers flying to George for the weekend ??? And if you try to cancel the flights, a total of R256 becomes available as a refund (total repayment from the airline). This was our second experience with this airline, I mean honestly ?
