Ghaziabad Nagar Nigam — broke a tile while cleaning the manhole

Address:

Ghaziabad, Uttar Pradesh, 201012

Hi,
Today morning some nagar nigam peoppe came to my home, 12/530, vasundhara, ghaziabad, to clean the manhole and broke a tile of my home's ramp. They also left the mud and garbage taken out of the manhole untidily despite of confronting them for the same. There is dirty sewage water has been logged out of house which is stinking as hell. Isn't this a duty of the nagar nigam people to clean the manhole and also the residue that has been taken out of it? Please suggest a way out and take a stringent action against this carelessness. Though our government aims to make our country, state, districts, cities clean by launching swachh bharat mission, but what is the ground reality? Has anyone ever thought about it? Request you to please pay heed towards this issue. Have attached below the photographs of the condition in front of my house.
Hope for a response!
Thanking you,
An honest taxpayer
