Address:

As per nhai rule kapalur toll gate located on 1.5 km away from tirumangalam municipality. After long fight with by the people, tirumangalam people got exception to pay toll by showing their valid driving licence with tirumangalam address. This exception got after long protest due to violation of nhai rule.
Today i paid the toll twice due to all the lane made as fast tag auto detection. Which is not appropriate. Citizen staying in thirumangalam do not need to pay any toll, because of vilation of toll plaza location. I want to get back my money which which was wrongly detected by toll plaza or it should moved into appropriate location to ensure the nhai rules. And i want to know the procedure to get my money back.
