National Highways Authority Of India [NHAI] — non fastag vehicles entering in fastag lanes

On pune banglore highway, khed shivapur toll and anewadi toll have a dedicated lane for fastag vehicles but those are kept open for all types of vehicles including non-fastag. They don't even bother that they are denying our right to save time and petrol using fastag on our vehicles. Workers at toll booth are very rude and mannerless. What the use of fastag if it takes same or extra time than regular toll lanes?
