Tamil Nadu State Transport Corporation [TNSTC] — M1p bus timing is not maintained in pozhichalur bus stand.

Address:	600074
Website:	Its not about the website its about Chennai MTC bus.

I am the one who uses the m1p bus departs from pozhichalur regularly. The bus timing is not maintained properly. Most of the time the bus will not come in the morning 6.50 first shift and in other days the timing is maintained very badly.
Sometime it will not come and some other days it will leave the bus stand at 6.40 or 6.45 before 10 minutes mentioned time by the mtc bus website. So that many passengers are not able to schedule their journey and arrive the destination properly because of not maintaining bus timing by driver and conductor.
Bus coming late to bus stand due to traffic or some other circumstances up to 10 minutes is acceptable but not coming or leaving 10 minutes earlier is unacceptable. If so then what is the purpose of time schedule displayed in bus stands and mtc websites?
Kindly instruct the bus driver and conductor to maintain the morning 6.50 am shift properly and of all the shifts.
