My tkt was from digha to garia by sbstc. Dep time 4 pm from digha on 15.8.2017. Tiicket no o[protected]. We boarded from contai & unfortunately we saw 5 persons occupied our 5 seats, i repeatedly requested the conductor how can they occupy the reserved seats. Pl tell them to vacate our seats. But the conductor didn' t bothered. Instead, he was arguing. After a long time he made alternative arrangements. So long my mother 78 years & my aunt 65 years & we 3 remain standing in such a overcrowded bus. Until and unless the ticket is cancelled, how can the conductor sell the reserved seats to other persons. Please look into this matter. Otherwise i'll be compelled to go to the higher authority.
