National Highways Authority Of India [NHAI] — toll amount deducted from fastag as well collected toll

On 14/02/2019 morning crossed TALAPADY toll naka, I was debited Rs 40.00 but while coming back at 5.10 PM, the same toll company debited Rs 15.00 in fastag as well as collected rs 40.00 in cash once again saying there is no balance in account; when in fact, there was balance present of 275.00 after deducting rs. 15.00. I tried explaining to the employee but he misbehaved. We were made to wait for nearly ten minutes and had to pay Rs. 40. Please go through record, credit amount of rs 40 to axisbank fastag account.
