volvo bus - Uttora service

recently I try to ride on volvo bus from Uttora to Motijheel. I brough tickets and wait. then wait, wait and wait. I can't see any volvo bus and waited for 30 minutes. then I return ticket and buy another bus's ticket. there were many people who were waiting and face the same problem. If volvo service goes like this way then I don't know how much profit they have targeted.
