Flight delay - no communication from airline to advise of the delay

I was booked on flight MN503, booking reference GBPBHI from Lanseria Airport to King Shaka Airport on Monday 03/09/2018, departure time 18:35. Upon my arrival to check in, I was informed that the flight had been delayed and the new departure time being 19:30.

Having received no sms or email to advise of this delay, I was a bit annoyed at this point as had I been notified, I wouldve delayed my arrival to Lanseria accordingly.

Furthermore, I emailed Kulula.com on ********** advising of my complaint and wanting to know how Kulula intends on compensating me for the inconvenience caused. On Tuesday 04/09/2018 at 15:12, i received a response from Elizabeth Maluleke from comair, apologising for the delay and confirming that compensation is only offered for delays of 3 hours and more. I find this to be unacceptable as a delay is a delay, immaterial of the time of the delay. I advised her that had an sms or email been sent to be advising of the delay, i would then have delayed my arrival to Lanseria airport accordingly.

To my suprise, I received an sms on 04/09/2018 at 16:13, advising of the delay and an email at 16:47 advsing of the same. Please note, all this, 1 day later.

I still await a response from Kulula.com/Comair with regard to the review of my complaint.
