Seat allocation problem in Indian Railways

Hi friends this post is about the issue my dad faced recently with Indian Railways.

I booked ticket through IRCTC for my dad to travel from Vellore to Bangalore with window seat option. The ticket got confirmed with window seat, please refer below image

When my dad got into the train and checked the seat 57 it was adjacent and he couldn't do any thing. He called me and said it's not window seat.

Later I sent email to care@irctc.co.in stating the issue, below is the reply from them
