National Highways Authority Of India [NHAI] — Palsit Toll plaza - West Bengal

I was literally Harassed by the Palsit Toll Plaza staff as they did not debit the toll amount by reading the Car No. The Fastag was not readable and hence without understanding the issue, they took double the toll amount as I paid it in cash. Really unable to understand why my car no. was not used for Fastag toll deduction.
