Indian Railways — Mismatch of displayed coach no in train with coach no in plat form

Address:	Koraput, Odisha, 763002
Website:	Indian rail

My boarding was in coach b4, train no.12802, puri-newdelhi express. We have reached in platform no.9 as per station display 30 minutes before. As per station display we r waiting train in station displayed b4. While actual train comes just before 15 minutes, b4 coach of train stands in station displayed s12. For reaching at b4 my family has to cross 12 coaches with huge rush, chances of missing the train also there, my kids and parents were crying. Its not a big deal to correct the displays of both platform with train. Mr prabhu ache din kab ayega, please take corrective action.
