Drunk people on flight of flysafair.

I just want to share my and my mom's experience with the rest of the people who use flysafair. My mom and I fly with flysafair from East lodon to Johannesburg in late December, there were ladies relaxing in the bidvest lounge from early hours, when we were on the run, they could not even walk as drunk as they were, flysafair's staff still allowed her on the flight. How can flysafair and staff allow it on the flight. The children on the flight was not safe.
