National Highways Authority Of India [NHAI] — Charging double amount irrespective o[censored]sing fastag

Address:

Mundiyar Toll, Baran, Rajasthan

Toll Place - Mundiyar Toll, Baran, Rajasthan.
They ask for double charges even when I have recharged fastag running in my passenger bus vehicles.
On asking why they charge, they say there server is not running. I asked them to charge reasonable decided toll amount then they started abusing and didn't let my bus pass the toll. On paying double charge they let my bus pass. I have a proof of my fastag balance and there receipt of double charge at one time.
Cash collection corruption is going over there.
