Dear,
I am a 64 years female, I had booked a ticket with my son on 30/08/2018 from BAPUDHAM MOTIHARI to Anand Vihar Delhi. I had selected lower berth on the time of booking but after booked of ticket you had alloted me to upper birth, how can I ascend on the upper birth at the stage of this age i. e. 64 years. Kindly change my seat from upper to lower berth as soon as possible because tomorrow is my journey date i. e. 14/09/2018.

Thanks and Regards
