National Highways Authority Of India [NHAI] — Extra amount charged in palsit toll plaza (NH#2) through fastag

Address:

Palsit Toll Plaza, Durgapur Expressway, Genraghata, West Bengal 713151

On 03.02.2021 while going to Kolkata from Durgapur (W.B) I crossed Palsit Toll on NH#2 on my car bearing Regn No WB40U 4765 at 0856 am.The amount charged was Rs 85. But I returned on the same day i.e. on 03.02.2021, and I crossed the Palsit Toll on my return journey at 04:12pm and the amount deducted through my fastag was Rs 85 again instead of Rs 45. How could they charge Rs 170 on both way journeys when I have completed my bothway journey within 24 Hrs. The toll charges for both way journey in the same day at Palsit Toll Plaza is Rs 130. Please get my extra amount refunded in my account.
I am providing photos of the messages of deducted amount as supporting documents.
