Indraprastha Gas Limited [IGL] — excavated pit for new connection left unattended

In my neighborhood people working for igl had excavated pit for giving png connection. The excavation was done about 10 days ago. They have left the excavated pit without backfilling it. I think they are not aware of the consequences of keeping the pit open for such a long period while as per the government order, no excavation can be done during monsoon period. I work as an engineer with government civic department.
You are requested to get the excavated pit properly filled with compaction and proper road restoration.
The address of the pit is as follows
98 - a; bharat nagar, masjid wali gali, new delhi 110025.
