National Highways Authority Of India [NHAI] — Forced to pay Double the Toll Charges when account was still available in Fastag

Address:	Devanahalloi Toll plaza
Website:	Fastagewam

My Regd mobile number is [protected]. My vehicle is Maruthi Omni bearing Registration Number KA 02 MB 8412. I have purchased fastag from Karur Vysya Bank, Nagasandra Circle Branch at Bangalore. I deposited Rs 600 in the Karur Vysya Bank, Nagasandra Circle Branch for which the bifurcation was Rs 100 charges or fee to issue fastag. Rs200 is refundable deposit and Rs 300 in my account to be used for payment at Toll plaza.
On[protected] around 9.30 am I crossed the Devanahalli Toll plaza in my Maruthi Omni bearing Registration Number KA 02 MB 8412 to go to Chikballapur. Toll was collected from my fastag.
The same day around 5 pm I returned from Chikballapur and wanted to go through Devanahalloi Toll plaza. I was Shocked to hear there was no balence. I WAS MADE TO PAY Rs 190 and cross the toll plaza.
How the 300 Rs could not allow me to cross Devanahalli Plaza within 24 hours only for one up and down journey is a mystery. This is broad day light Robbery. How to get my amount refunded is not known to me. My email Id is [protected]@yahoo.com. If I dont get a reply, I will send this email to National Highways Authority of India and complain this DAY LIGHT ROBBERY by the Fastag.
