I had to contact someone about something in regards to my Adsense account. Submitted the ticket 4 times - once every week. Got automated responses, and no human reply.
My G+ account has been "under review" for 4 months (no shit). I feel helpless because there is no way of contacting a human (or even a machine for that matter) about this.
I had a glitch with one of my apps on GAE, again no support!
For a company this big, you'd expect them to have decent support by email AND by phone.
