Shocking Fly Cemair Service

On the 11th of April, we booked a flight for my wife, to fly back to Cape Town from Durban, with boarding policies my wife was at the airport 2 hours prior to the flight at 19:30pm, closer to the time off flight departure she saw on the notice boards that the flight was delayed for 45 minutes, which she felt wasn't too bad, but then it got worse, the flight was even delayed further till 22:10pm, which now meant my wife was sitting at the airport for 5 hours, to make matters worse i sent an email to Cemair to fin out what's the reason for the delay or what they going to do to not have these sort of delays in future but had no response since my email on the 11th of April, I will not recommend this company to even my enemies, this was the first and last time I will make use of them, their communication is absolutely poor and no regard for their passengers or clients. Maybe if they offered these services for free I would have understood the level of service but its a service that was paid for and the whole experience was shocking.
