National Highways Authority Of India [NHAI] — Fraud while debiting money through fastag

Address:

Shambu, ambala, haryana

I was going through shambu, ambala toll plaza in morning at around 8:00 am in lane 3. When we stopped our car there there, girl on duty said us that please wait fastag isn't working. Another person on duty there said that fastag balance is low please pay it through cash . I paid the cash there in hurry but then out of concern I checked my phone notification. It showed that 75 rupees debited from my account. When I notified them money had been debited through fastag, they acted rudely and started giving excuses that we have to give 150 rupees cash . We showed them message multiple times but they keep on doing drama to sucessfully fraud us. It took us almost half hour to clear the issue meanwhile other people in lane also waited as we are resolving the matter.
These malpractices should be stopped.
If we have to struggle so much in paying even after having fastag due to this malpractices going on to earn extra money by fooling people then what's the benefit of this service.
The people concerned there should be checked and scolded for such henious acts so that they restrict themselves from fooling common people further.
