South Bengal State Transport Corporation [SBSTC] — did not receive e-ticket after online payment

This is very dissapointing. I decided to book my journey ticket from sbstc website and did so for 13th of this month from burdwan to karunamoyee and booked the bus which will leave from burdwan at 5:50am. I have booked through net banking and after the payment is successful i did not receive the ticket in my email id nor i have got a message. Now its an issue as i won't be able to show the ticket to the conductor. Even if you tell your problem they will not listen to it and ask for extra money though you habe already booked the seat. Please do look into the matter as i am not able to see my past bookings in the history portal even. My email id os sus. [protected]@gmail.com.
