Check Google daily for rejected call extensions

The feed services objects all have a "status" attribute that is Active, Deleted, Unknown. When feeds are created, the status is "Unknown" for new items and then an hour or a day later (from my experience) it gets set to Active.

We need to do research to determine if feeds can be rejected by an AdWords editorial team and if we need to poll for rejected feeds like we need to for ads and location extensions.
