2) I'm a little sympathetic to Google here, because there's no way that they can offer real customer service to the entire Internet. I run some small businesses and get dumb phone calls all of the time from confused people thinking that my random shop has anything to do with their phone plan or email issues or a problem with their cable bill or anything else under the sun because they ended up at my store after putting certain keywords into Google. I have no doubt that Google would receive hundreds of thousands of mostly dumb, useless calls daily that they are not responsible for from every confused person out there. There's no feasible way to provide standard customer service to the entire Internet.
3) The solution for Google is really easy though: charge some fee for human support that keeps customer service requests to a manageable level. When it's a genuine issue, people will pay some fee to get an actual trained person to pay attention to and hopefully resolve.
4) I'm sure people have committed suicide and lost jobs because of the consequences from Google blocking their account without any recourse. This is definitely not an acceptable state of affairs, and I'd suggest avoiding using Google products whenever possible until this reprehensible behavior is changed.
