National Highways Authority Of India [NHAI] — Hefty toll tax collection twice on 75 km distance

I am a resident of Nagaon, Assam- 782002. For traveling from nagaon to guwahati we have to pay toll twice for distance of only 75 kms. One toll at Raha and another at Sonapur. For such small distance a total tax sums upto around INR 300. It hurts the common man to pay such hefty taxes.
Moreover the situation worsens for people who have to visit Chaparmukh or Raha. The distance from raha toll gate to chaparmuk is no more than 10 kms. Even then they have to pay around rs 100 tax...even if they return within 2 hrs. This is a big problem for the common man. Kindly loom into the toll tax and reduce it to an acceptable amount.
