I had booked online ticket of semi luxury bus from maitri park to pune station. The bus for supposed to reach at boarding point at 6.05pm. I arrived in time but came to know that i was transferred to the another bus which left before this bus. I wasn't given any notice about this neither through phone call, nor sms nor email. I was later being transferred to a bus which came at 7.30pm. By the time i reached pune station it was 11pm and i couldn't find bus to go ahead. It caused me great inconvenience. Kindly take an action against this things.
