Hi Navneet,
This seems like an issue that you should resolve with your company, since they seem to have done the set-up for the others projects you describe as working properly. Another option is for them to
open a support ticket. Another option you should look into is
contacting Billing Support. Finally, the limited advice I
can give is to look in the Developers Console for your project (insert your app id):
https://console.developers.google.com/project/<your project id>/settings
Here you can check which billing account is associated with the project (it should be your company's).
Other than this, I'll remind that this isn't the right place to look for billing support. As mentioned above and in previous threads, you should contact Billing Support to get something like this resolved. The purpose of this forum, the Google Groups App Engine forum, is to have general and high-level discussions of the platform and its services, not for one-on-one support.
Best of luck!
Nick
