MTC Group — irregular frequency of service

Address:

600081

I have been commuting 159a and 159e service mtc buses via koiambedu to t-h. Road. Sir past two weeks those services have not being from 06:00 pm to 9:10 pm and also the frequency of those services are seldom. Also the night service frequency is very poor. But the 15b services in night time is high and all the buses are running empty. Even the time keeper at koiambedu terminus doesn't know when the night service buses are scheduled.
We at north chennai people always neglected for the welfare by officials.
Please look into it and do the needful.
