Indraprastha Gas Limited [IGL] — Installation of New Connection at my address

Address: sector xu 3, greater noida

I applied for a new connection on the 6th April. For which I had to subsequently follow up and got the documents submitted two weeks later, because no one from IGL cared to reach out to for the same.

Such a laidback service. I had to later follow up for the next steps as well. No one from the induration team did reached out to me. The payment was done on the 27th April.
Now we are sitting across half of May and the connection has not yet been installed.
Please give me a contact to raise a grievance and get this escalated.
