Cancelled Flights, frustrating Airline Company

Can someone investigate this company and really find out what they are up to. It really is unacceptable to allow an airline company operate the way these people do. I was supposed to fly on 11th oct at 8am. only at check in did they inform us that the flight and all other flights for the day have been cancelled. I immediately had to purchase new tickets for my family and I from another airline company which cost me over R7000. How can they just go on behaving like this to people. It is very clear these are not isolated incidents!!!
