If you manage to figure out the incantation to email an actual person, they're some kind of 1st-level support whose purpose in life is to piss you off so much with useless pre-canned responses that you finally give up.
Truely, incredible that they get away with it. Also incredible that they're OK with this given how much profit they make from ads.
By comparison, I've had excellent support from Bing Ads in the past - unfortunately they represent a much smaller number of impressions than Adwords.
