Tamil Nadu State Transport Corporation [TNSTC] — request to check condition of the bus

Hi,
I am travelling from puducherry to chennai on 10th february. I boarded the bus at 10am from bus stand. Usually it will take 3 hrs to reach chennai (Perungalathur eta 1:00pm). But we only reached chengalpattu at 1:00pm which is too late. This bus is very slow and when asked the conductor, he said the bus is not in good condition. I request you to please do proper checks for the bus before making it functional. Bus no.: tn 21 n-1400. All the passengers in the bus were complaining about it.
