Individual — fastag sensor not working / rude behavior of the people at the toll

We frequently pass through the sriperumbattur toll plaza and most of the automatic sensors do not work. Vehicles get stuck for a very long time. Further the people at the plaza are so rude and unpolite who refused to open the gate and held us unnecessarily this morning when they were questioned why there is a delay in clearing the vehicles. They were acting so wild, blocking the vehicle to make note of the number. It was such an unpleasant experience inspite of we spending so much on the toll and frequently crossing it every week.
