Can we trust Flysafair? Flight FA234

Was booked on flight FA234 from Johannesburg to Port Elizabeth. Captain had to ABORT TAKE OFF on the runway!! (explanation technical fault) - returned plane to parking bay were all passengers disembarked. No communication from crew or ground staff as to what was going to happen. Safair found another plane and all passengers boarded BUT problems again!!! Captain got technical help and was cleared to take off! BUT guess what this plane had problems to and all passengers has to disembark!! Serious concerns with Safair safety, maintenance and service if 2 planes could not be used. LOTS OF VERY FRUSTRATED AND NERVOUS PASSENGERS!!!!
