National Highways Authority Of India [NHAI] — Regarding cash receipt at toll plaza instead of fastag

Dear Sir,
I crosses your toll plaza at Kota Bypass (Hanging Bridge) from last 2 months. Most of the times they collect toll in cash. Maximum times at one side of toll gate fastag is working and when I returned they charged me in cash also vice versa. I am having more than 30 receipts for proof. They simply tell fastag reader is not working due to this I have to pay for return journey Rs 65 for one side and Rs 50 for other side I.e. total 115 instead of Rs 100. When I asked regarding this they are not giving any reply. 5-6 persons surrounded my car. I am a daily commuter. Also due to this there is always jam at the toll gate. After having a valid and functional fastag I have to pay more on daily basis. I have also kept all toll receipts. Kindly do the needful, so people like me don't suffer from the misbehaving of the toll staff and extra charges they collected from public. I am working as manager in a public sector bank so i have to cross the toll daily, I have no other option. A positive response is awaited. My vehicle no. Is RJ45 CE 1000 and my contact no.
