NHAI — Excess charge deducted-refund.

I Crossed valavanthakottai toll plaza on[protected] at 17.24.54. In car no. TN 02 AY 4972. My vallet balance before entering was Rs 990/- they deducted 65/- the balance in my vallet should be Rs 925/- but it shows 825/- Thus they have wrongly deducted Rs.165/-instead of 65/- Please rectify the mistake and reverse Rs 100/- to my vallet account no.
