National Highways Authority Of India [NHAI] — Toll charges deductions for exempted vehicles

Address:

Khed Shivapur Toll plaza, NH4, Pune.

On Khed Shivapur toll plaza on NH 4, ON Pune Bengaluru highway, The Pune vehicles with MH12 registration are exempted from toll.
But the toll amount is purposely deducted from fastag account without our knowledge. While passing through the toll plaza "Ex. Vehicle, not paid " message is displayed on the LED board. and after some time we get the message of deduction of toll from our account. The fastage agency do not take any responsibility for this. The toll is deducted by entering the vehicle no. in the system which is a clear loot of the customers. on 16th December 2020, I had covered the fastag sticker with non transparent paper while passing through this plaza, I got pass by message as above. but next day I got sms of deduction of toll.
This is happening with me 4th time, I raised this complaint with customer care but the case was closed without giving me refund.
Please take strict action against these looters and save the money of vehicle owners from Pune.
