Municipal Corporation Of Delhi — drainage system of house

Address:

New Delhi, Delhi, 110060

I need an scavanger who can clean my house drainage system.. It's very unhygienic and unhealthy. Even we are not able to use washroom as well. Hope you will surely take action. I m continuously trying to call municipal but number but no one is responding. Atleast there must be quick response which is not.
Day by day problem is increasing and creating problems
