Airlink bad service

On the 13th of December, I flew to Pietermaritzburg on the midday flight only to be returned to OR. We took off at 16:35 on to be sent to King Shaka, no communication whatsoever. Last night the 16th of January, the flight to Pietermaritzburg was cancelled, no explanation. This morning, I booked a 6:50 flight and its is now 7:40, still here at the airport because we can’t take off. Their service is very bad, this is the last trip for me with them 😡😡😡
