National Highways Authority Of India [NHAI] — cash vehicles being entered in fastag line

Address:

h.no.453 1st floor , sec 10 Gurgaon, 1st floor, 122001

Dear sir,
My self ravinderjit singh. I am daily commuter from gurgaon to fridabad. I have been using fastag purchased from gf toll plaza for gurgaon faridabad toll road. I have been traveling from this toll since one year. I am facing problem in tag line since then as cash vehicles are being allowed to enter in fastag line while it is govt. Rule not to allow cash vehicle in fastag line to avoid any waiting. I have requestd toll staff many time and now i have put mail to them on its mail id on 9th feb. 19 but till date there is no resolution. So i request to nhai authority to resolve this issue.
Thanks
Ravinderjit singh
