National Highways Authority Of India [NHAI] — Refund of toll and fastag reader

I m gone through khondali toll plaza i have balance in my fastag account and it is debited also but toll manager said you have to pay by cash because it is not showing in our system and i paid 120 rs cash and 60 rs also cut through my fastag account. So instead of 60 rs i have to paid 180 rs means 120 rs extra because of toll system not working. Its toll plaza fault that i have to go through.so refund my 120 rs of toll.
