National Highways Authority Of India [NHAI] — Im complaining about double charge

Address:

Surathkal toll plaza, Dakshina kannada,Karnataka

When i passed through the toll gate they deducted 55 rupee through fastag. I returned back to that toll gate after 1 hour l, so that means they have to deduct 25 rupee, but they deducted again 55 rupee.
I want my money back.
Below i attached some details.
