Airtel — unauthorised digging of road and footpath for laying cable

Address:

600041

I live on dr. Radhakrishnan nagar main road, thiruvanmiyur, chennai - 41. A few weeks ago, airtel linesmen dug up our world-class road and footpath to draw a cable across the road to the airtel box on the opposite side.
The cable goes under the road and the digging is visible on the surface of the road. The surface of the road remains broken.
Then the cable goes on top of the footpath to reach the blue box. The airtel linesmen have crudely covered it with a splash of concrete. This has formed a bump on the footpath and people constantly trip over the ridge-like concrete cover. The corporation official came and inspected it and said no permission has been obtained from the city corporation to dig the road and the footpath. Such permission is mandatory in chennai for digging a road. And ours is a new world-class road.
I have attached pictures here.
I shall lodge a police complaint against airtel, chennai for damaging public property and digging the road without official permission.
