    I am a Norfolk Southern employee original appointment for 11/6 but had to cancel due to family emergency given new appointment on 11/15. Aon gave the appointment, but on 11/11/19 canceled and gave me an appointment on December 9. I protested and they now can not find an agent before the close out date of December 7. This will be the 19th year of dealing with Aon and the scheduling and communication is getting worse each and every year. Help! Can someone please contact me before the Dec cut off date for open enrollment?
