National Highways Authority Of India [NHAI] — Illegally Seizing of vehicles by toll plaza staff

My vehicle Eicher bearing number mh47 y 2979 travelling to and fro boisar illegally impounded by the khaniwade( Maharashtra) toll plaza staff today (13/2/21)
They claim that the fast tag attached to my vehicle is not right and i will have to pay more than a lakh of rupees as penalty if i want my vehicle to be released.
This is actual gundaism by toll plaza employees.
My vehicle is transporting hardware items for factories along with perishable items which needs to be delivered today itself.
There will be a huge loss If the vehicle is not released immediately.
HOW CAN THE TOLL PLAZA EMPLOYEES IMPOUND OR SEIZE ANY VEHICLE???
My vehicle regularly pays the toll via fast tag.
The fast tag have been attached to my vehicle by the Eicher company itself before the vehicle was delivered to me.
How am i at any fault if there was any mistake with the fast tag?
How can the toll plaza employees demand lakhs of rupees to release the vehicle?
It's already been more than 2 hours since they have impounded the vehicle.
