I'm working on a C# application that needs to check and display electricity bills for users of the Islamabad Electric Supply Company (IESCO). I would like to integrate an online bill checking feature within my application.

Could someone provide guidance or examples on how to:

Access IESCO's online bill checking service programmatically.
Parse and display bill details (e.g., due amount, due date, bill status) in the application.
Handle potential issues such as network errors or invalid input gracefully.
Ensure secure data handling and user privacy.
Any code samples, API documentation, or libraries that can facilitate this integration would be greatly appreciated.
