Pallavaram Municipality — Road digged up by neighbour

My neighbour connected his house sewage line to the main line by digging the road in front of my house and did not close the dug up area properly.
This was done despite an official from the municipality informed them to close the dugged up area with concrete.
I request the concerned official to take up this matter to restore the road as it was earlier
