Pilot Should Be Suspended With Immediate Effect!

Last night, i was on a flight from CPT to JHB(flight FA-217), departure @ 17:20(date :2021/01/04) The take off was pretty smooth. Though about 15-20min into the flight, the plane was extremely unfomfortable, to a point where most of the passengers started screaming. The pilot was driving the plan at extremely high speeds. It happened on numerous points on the flight. The landing was even worse. Ive been using FlySafair for a while now. I hadn't encountered anything like this from them or other air lines till last night. We thought we were going to crash. That's how bad it was
