The bus 500CA does not operate as per the details given by BMTC. I was waiting at the ITPL bus stop from 7PM to 8PM. Not even one 500CA came in this period. Multiple 500CA buses were going in the opposite direction. These buses are changing the route number to 500NA and coming to ITPL. This is peak hour and the frequency of this bus should be more at this time rather than at 4 PM to 5 PM. This is a very serious problem for the commuters on regular basis. Kindly address this issue immediately.
