NO NOTIFICATION OF FLIGHT CHANGES

I booked flight MN0620 for 21 June. Only on receiving my flight reminder did I see the flight has changed. No one has called, tried to call, emailed or SMS'd to tell me of this change. I shouldn't have to check the reminder email, most of the time these are ignored because I WOULD KNOW WHAT I BOOKED. When were you clowns planning on telling me you couldn't stick to the time you advertised. This is unacceptable and a complete display of incompetence to not even bother to inform customers of changes in flight details. Good luck, in future I will not use Kulula nor will my family and hopefully friends. Mango will have my business from now on. *****s...
