Mango je715 delay

Worst ever airline Always delayed Ive taken so many flights this past year and I've never had any issues with fly Safair but mango has been delayed every single ****ing time, and not by a few minutes, by many hours, I'm missing a university exam due to the delay in the flight as I can not fly at 6 in the morning, this is pathetic I am opening a Facebook group to boycott mango airlines as they need to be permanently grounded
