RTO India — Wrong E-Challan - Ganjam OD RTO

Hi,
We tried to pay the NP tax at our RTO recently. But the RTO officer mentioned, you have E-challan on 25th Sep 2020 given by Ganjam, OD RTO. The Drivers are confirmed, during the date we didn't stopped by any of RTO at the place and didn't receive any challans.

While verify the challan details, mentioned as "Excess Speed". The truck speed limit 50KM only and verified using truck GPS. There are no schools at nearby area and no chance to go behind the school buses.

I have sent two emails to RTO Ganjam & ori transport commission, but no response.

So, Please clarify the below:

1. Please share the over speed evidence with school bus.
2. As per the rule, first time will be 2000Rs and I have received 4000Rs. May I know the reason for 4000Rs?

Thanks,
Arul
