National Highways Authority Of India [NHAI] — Double charges at toll gate while sufficient balance was in my fastag

It's about NEEMRANA toll plaza, on dated 27th Feb 2021 when i was reached on toll plaza the operator said to me my fast tag is black listed so he can't be allowed to cross the toll. I paid double the amount to toll gate operator 135x2=270 Rs. any crossed toll, for your reference toll slip attached. After that I tried to contact the toll free number but it was not connected, which may be a network issue. After reaching my destination, I tried again then spoke to the customer care executive as per him minimum balance 160.00 Rupees is mandatory as per NHAI they can't do anything. Its government regulation customers have to maintain a minimum balance of one hundred sixty rupees.
My FASTag balance was 148 Rupees and toll charges was 135.00 Rupees. As per below information FASTag user no need to maintain minimum balance for FASTag users .So kindly refund me 135.00 Rupees extra charges which was paid by me on NEEMRANA toll gate on date 27th Feb 2021.
