Today 30th oct 2016 i booked 3 online ticketand ticket no L[protected] and seat no 24, 25, 29 from kolkata to arambagh but at ticket counter the concerned person told that 11am bus is not available and we need to board 11.30am bus though bus no wb39a 1890 was available in stand from 10.45am.This is not the first time i faced this problem, earlier also i booked 11 am tic and i was forced to board at 111.0 am bus as 11 am bus was nit available like today.
If 11am bus is not available every time then why 11am bus booking can be done online.
Me and family are in urgent situation to reach my home town arambagh as my family member is not well but with this type o[censored]nprofessional schedule of sbstc is really causing lot of trouble to people.
