Earlier quoted context omitted.
Well, the advertisers I know have their share of Google complaints as well relating to customer service.
I'm sure if an advertiser spends $10M a month on Google ads, they have someone's cell phone they can call anytime if there are any issue, and that person will "fix" whatever the problem is. These are the Google customers, not the guy who spends $50 a month advertising his self-published book.
If Google wants to treat such low priority customers like non-entities, they are free to do so, but lets not pretend like they should act this way, because they shouldn't. It might be fine for them to do this in the short term, but in the long term it bleeds a lot of good will, which eventually catches up with every company no matter how big.
