Two points: 1. This is not a problem with Google's Customer Service, it is a problem with their vendor relations. When Google publishes ads on your site, you are selling that space to them. Google is your customer and isn't obligated to tell you a damn thing except that they don't want to buy from you anymore. 2.

My strategy with advertising is more to say "hey, look at me, I exist" Once you know I exist, the price differences between my competitors and I give you enough reason to research me a bit more, and perhaps give me a try. So personally, I care more about cost per impression than cost per click.
