National Highways Authority Of India [NHAI] — arrogant behavior of tasawade toll plaza employees

I was travelling to karad(Dist. Satara) by NH4 with family in my car which has a valid fastag with appropriate balance. When i reached Tasawade toll plaza i approached to fastag lane which was too slow as the scanning machine there was not working properly as usual. I took my vehicle in front of the scanners and i saw the amount deducted as a toll fee and i started to passaway but the arrogant employee on the booth thought that i want to miss the toll fee and i m going forward without paying so he asked his GUNDA like collegues to stop my car...here one of them hit his hand very badly on my car's wind shield which got a crack...i request the authority to strictly warn their employees not to harm like this to others vehicles...the employees here in this particular toll plaza i think are GUNDEY in nature and should be removed from work immediately
