IGL — igl connection leakage

Address:

Raksha Addela, F-704, gaur city 2, near 16th avenue road, greater noida wes, Gautam Buddh Nagar, Uttar Pradesh, 201308

My bp number: [protected] got installed in november 2018, and since installation it keept leaking as installation checks were not done and our lives were at risk for nearly 3 months.

I want to raise complaint against complacent nature in which igl connection was installed and also want to know who would be responsible if something misshapen had happened.
On top of it, i have been charged for the leaked gas, which is around 12k.
I demand compensation from igl for putting lives of my family at risk.
