National Highways Authority Of India [NHAI] — WPE TOLL TAX KHARKHODA, Staff are forcing to pay after their system down.

I was traveling from Manesar to Kharkhoda. I was entered from Manesar through Fastag and trying to exit from Kharkhoda. But at Kharkhoda toll plaza, their system was down and they are forcing to change the lane or pay cash which I denied. Those guys have wasted my 30 min at toll. And after complaining to NHAI they have exempted the toll meaning they exepted their fault. After wasting my 30 min they opened the toll. I need an answer why they had done this to me. I was in emergency situation at that time.

Need reply ASAP
