Indraprastha Gas Limited [IGL] — Detail bill not generated in past 2 months

Address: E-219, 2nd Floor, 4th Avenue, Gaur City-1, Greater Noida Extension, Greater Noida-201009

BP No: [protected]
I had shared screenshot of my meter on 4-Mar-25. Short bill was generated 1-May-25 for Rs. 1500 approx. I called the helpline number for detailed bill and they told that it would be generated in 48 hours. Today, 4-Jun-25, I have paid Rs. 1600 (with Rs.100 late fee) because the due date was 20-May-25.
But the detailed bill is still not available on IGL website/ Watsapp helpline number of 1800 helpline number.
Last time, they had added my previous amount also even when I had paid it in full, I had to get that corrected and this time again they have made me pay the bill without giving any consumption details.
This is total fraud system going in IGL.
