National Highways Authority Of India [NHAI] — Poor quality Toll plaza

I have travelled from Belgaum to bangalore on 7th May 2021, my fastag was scanned in all toll plaza except the Hebbalu toll plaza which is section between doddasiddanahally to hadadi. Their scanning equipment's were looks like in very poor condition and were not properly maintained. Though in few toll plaza's, it was shown low balance but eventually it was scanned in couple of seconds but hebbalu toll plaza was never able to scan. Not sure if this hebbalu toll plaza is making the people fool to collect double fee, because I never face this scanning issue in the toll plaza's which came after this toll plaza. Attached the payment history and receipts for the reference, please look into this issue.
