National Highways Authority Of India [NHAI] — Extra charging and misbehaving

Address:

Nawabganj toll plaza Kanpur Lucknow highway

Sir,
I am a serving defence personnel of Indian Air Force. I am presently posted at Air Force station Barnala Punjab.
On 27 Dec 2020 I went to Lucknow by my personal car to drop my son at Lucknow Airport to catch flight to Mumbai.
During onward journey I was allowed to cross the toll plaza at Nawabganj toll plaza situated at kanpur Lucknow high way without charging any money on production of my defence personnel identity card issued by Min of Defence.

But during return journey I was charged double amount Rs 150/- vide reciept no [protected] stating that your car is not bearing fast tag. When I told that fast tag is compulsory with effect from 01Jan 2021 they started misbehaving. They not only forfeited my legal right but also harrashed & humiliated me mentally.
In the context of above it is requested that a strict disciplinary action maybe initiated against the guilty toll plaza personnel. Also refund of money paid by at toll plaza with penalty for the misbehavior and forfeiting my legal right may be paid
to me at the earliest.
An early action will be highly solicited.
