VITALITY DISASTER TRYING TO RETURN USING MY VITALITY DISCOUNT

WHY AM I UNABLE TO BOOK A ONE WAY TRIP BACK TO JOHANNESBURG USING MY VITALITY DISCOUNT? THE SERVICE FROM THE VITALITY DEPARTMENT IS TERRIBLE. WHEN I PHONE IN TO QUERY IT, NOBODY KNOWS WHAT I AM TALKING ABOUT AND NOBODY CAN HELP ME. THAT IS WHY I AM POSTING MY COMPLAINT HERE. MAYBE SOMEONE WILL BE ABLE TO HELP ME NOW.
