Municipal Corporation Of Delhi — all drainage blocked

In j. J colony block e rohini sector 24 all drains are blocked. And now condition getting worse because water comes out from drains. I complaint many times to supervisor but he never came to check what is the matter. The drains of entire block is closed. It happened only with local people because we have no power and the supervisor does not work until there is no pressure on him. One more thing many times supervisor's worker demand money from local people for their work. Please solve this problem
