CHANGED MY SCHEDULE WITHOUT PROPER NOTIFICATION

I made a booking online on the 23rd September for a flight departing on the 31st December from OR Tambo at 19h30.<br> <br> Mango then changed my flight schedule (on the 11th November) from 19h30 to 17h10 AND DID NOT NOTIFY ME.<br> <br> I must have spoken to 3 different people who could not explain to me how my flight was changed without them notifying me, they said they probably would have sent me a mail 72hrs before my actual flight date. Now what good would that do me because that would have been too late for me to make any other form of plan to get to KZN.<br> <br> I am really shocked and disappointed that this is the type of service you provide to loyal frequent flyer customers.<br> <br> Can anyone explain to me how you can change peoples flying information and not notify them immediately so that we can at least make provisions.
