National Highways Authority Of India [NHAI] — excess toll charges

Address:

B1A Jaysri Park,Behala, Kolkata, West Bengal, 700034

On 28/12/2019 at 21:00:17 i paid rs.155/- for up and down toll at dhulagarh toll plaza ten. No.[protected], lmv registration no. Wb02ab5726.
On 29/12/2019 while returning entered the toll plaza channel before 8.45 pm. There was inordinate delay and vehicles were not moving. At last when we reached the counter the person, concerned (Chandan) refused the up& down payment receipt, did heated arguments with us and forced us to pay rs.105/- again, trn no.[protected], time clocked then 21:25:21.
Why customer should pay for the delay at the toll plaza?
I request the nhai to refund rs.105/- and apologize for misbehavior of the concerned person and also compensate us for the delay.
