SA Airlink. Cancelled flight

Flight from Mthatha to Johannesburg scheduled for 17:40 has been cancelled due to "Technical Problems . All passangers told that they will arrange a flight in the morning. When asked about accomodation and transport, the reply was" Not our Problem ". Thus is unacceptable as the delay was their fault. They also claim to have notified all passangers of the cancellation. This is not the case. They need to cover additional expanses incurred insofar as accomodation, vehicle rental and meals for the passangers. What happened to Customer Care????? I am disgusted at the responses given....
