Worst Mango Flight

On Thursday the 1st of March 2018 was booked on the Flight JE 259 from OR Tambo to King Shaka the departure time was 16h05 the flight was delayed for 1 h45 mins while the flight being delayed the boarding gates were changed three times .Eventually i boarded the flight my seat number was 28D.This was one of my worst experience with Mango the sliding button/knob was not working so the seat was sliding front and back uncontrollable all the way to Durban ,imagine was what happening during take off,turbulence and landing
