National Highways Authority Of India [NHAI] — Because of minimum balance I have been forced to pay double charge.

I have money in my fasttag account. But my card was suddenly made Inactive because it says minimum balance rs 150.

Even though NHAI has announced there is no need to maintain minimum balance, I was forced by vijaya mangalam Toll plaza Employees in Tamilnadu to pay Rs 110 as double charge.

NHAI should clearly give instructions to Toll plaza employees. Banks also has to be informed.
This is causing unnecessary trouble and difficulties, hassles in Toll gate.
