I've just had, for the first time in my 5 year history as an AdWords advertiser, reason to use the "Contact Us" feature through the AdWords interface; as 75% of my campaigns have -at some point since I last logged in- been disabled for "Ad Text Trademark Term" despite the ads containing nothing but generic terms (besides i'm not even trying to target trademark terms)
Anyway, I went Help > Ad Approvals and Policies > Proceed to contact us... and there is a box labeled:
"Summary of the issue"
...so I gave a 4 or 5 word summary expecting there to be a form on the next page on which to give comprehensive details of my support request; only to see a "Thank you, we will get back to you ASAP!" message!
