IRB Infrastructure — Double deduction of toll

I have been travelling from Talegaon. My fast tag of HDFC Bank [protected] was deducted with 203 rs at Talegaon toll. After this the fast tag balance went low. At the Khalapur toll, since th balance was low on the way and as internet was not working, i made cash payment. As i have already made a payment of rs 203, i should have been charged rs203. However, I'm charged rs 406. When asked for the lady informed that it is already punched, and that's how it is and she cannot consider the earlier toll paid at Talegaon even after showing the message on mobile. Then another employee Mr Mahesh Patil said this is how it is and they don't consider the earlier payment made as the receipt is punched in. This is inappropriate practice. It is possible that the toll balance gets low on certain occassions when you are travelling. That should not be a reason for double deduction of toll. Request to refund the extra toll deducted at the earliest. Attaching the message as well as the receipt for ref.
