National Highways Authority Of India [NHAI] — Taken cash at toll plaza

On 29 December My Old age parents are travelling from Mouda-Nagpur to Bhopal (NH-69)
At Patansawangi toll plaza, toll operator denied for fastag payment and took money Rs 180 which is doubled than usual amount of Rs 90.
For your reference I am enclosing here the attachment in which it is clear that payment in fastag account is sufficient even before start of journey and fastag is in active condition.
Payment deducted at toll plaza Mathani which is 54 Km before Patansawangi toll plaza and at Khambara toll plaza which is 83 Km after patansawangi is by fastag card only.
The behaviour of Patansawangi Toll plaza team seems notorious as their conversation with my parents is disgraceful with foul words (recorded in dashboard cam). operator at patansawangi intentionally cheat the my old age parents and taken charges in cash of Rs 180.00.
The case seems to be of insufficient services. If correct measures against Toll plaza operator will not taken by you than I am compelled to file a case in consumer forum.
