No compensation for delayed flight

I was booked on flight JE249 departing to Durban at 9:50am - after check-in, I was notified of a 3 hour delay. I needed to be in Durban at 11:30am, so waiting for this flight was not an option. After contacting the staff at the Mango counter and at the gate, I was notified that there was nothing they could do - my options was to either wait for the flight, or book a flight with another airline.<br> <br> I ended up flying with SAA on their 10:15am flight.<br> <br> I contacted Mango Airlines on 13 April 2016 to find out if they offer any kind of compensation, as I had to pay a significantly higher ticket price as a result of their technical issues. I was informed that there was no compensation, which I find extremely unfair as the delay was there fault.<br> <br> I find the treatment of their customers highly unacceptable - I accept that problems happen, but the way it is dealt with is key. <br> <br>
