ground crew passing the buck then an aggressive air crew member

FlySafair's treatment of passengers is disgusting. Overbooking flights and then bumping passengers who booked weeks in advance is terrible service. Trying to fix the problem was passed from one person to another on the ground. When we eventually got a flight, it turned out the ground crew had not informed the air crew. To make matters worse, the attendant became very assertive and demanding to know who let us in.
