Indian Railway Catering & Tourism Corporation [IRCTC] — booked tickets for my old aged parents but got upper berths

Address:

560043

I have booked 2 AC tickets for my father and mother (age 59 and 54). 71 tickets were available at the time, still I was assigned upper berths. I am worried about my parents. Who will climb and sit on upper berth for 30 hrs journey at the age of 60. I called the 24*7 customer care for help but no positive response. Kindly help me out.
