Any google network admins out there?

[Randy <nanog () afxr net>]

I've started to get some message today from google claiming that my 
computer or network was sending automated queries, and they are blocking me.
I'm not sending automated queries, Ive logged all of my outbound traffic 
and there is only my browser traffic going to google.

I'm not responsible for any one else on "my network" since it is owned 
by my ISP, and solely blocking me based on what some one else with an ip 
address close to mine is not an acceptable practice to have for an 
address used for personal web browsing.
I would like to know if there is any way to get into contact with google 
about this other then by legal means?
