In a case like this, that is a bit tricky. This could be Joe (or Jabul) Random Googler in India on a lark. Or it could be something organized, probably at a small level.
Contacting someone in Google Maps might help -- this would at least be a business unit that has some interest in not generating ill will. Google IO is a conference with lot of Googlers. There's a presentation about Google Maps, and if they aren't the right people to talk to, you could probably ask them who a good contact would be: http://www.google.com/events/io/2011/sessions/designing-maps...
PR people are usually a very good contact. News can break 24 hours a day, so they're usually very available. If you're about to spill the beans on something that can be very embarrassing, they will connect you with the right person. If they don't, they're on the hook for cleaning up the mess.
that says they didn't copy results by looking at google directly, but by watching users that use google.
With the number of IE users, the difference is only in how they achieved it, not whether they did it.
Provide actual facts for a start. Currently they are just pointing the finger without any kind of explaination as to how they came to their conclusion.
I disagree: Actually the best way to get answers from a too-big-to-communicate company like Google is to make the whole process as transparent and out in the open as possible.
Google is notoriously difficult to contact for most people. One of the best ways to get them to respond is to let as many people as possible know about the issue at hand.
I've managed to contact a few different organizations in a few different ways.
I'm no fan of Microsoft (check post history), but when I found that a large volume of 419 spam was coming through Hotmail some years back, I looked up their main switchboard number, called, spoke briefly to the receptionist asking for the VP of the related unit (I'd looked up his name). She transferred me to him. He picked up on the first ring. I explained the situation briefly, we spoke for a few minutes, at the end of which he said he'd put me in touch with the guy who could fix things. Fifteen minutes later I was talking with him, and we exchanged information over the next few months as I helped him plug his holes. I am still highly impressed by the professionalism demonstrated at all levels. I'd also worked with Microsoft to resolve a GPL compliance issue (again, directly contacting the appropriate VP) again with minimal fuss.
A southeastern US university IT contractor who's private business was spamming me (and he was denying it) ended up with a series of emails escalating up the academic food chain, ultimately to the university president (.edu websites are, or at least were, wonderfully information rich). I eventually got the response I had hoped I'd get on first contact.
Another issue involving AOL at which numerous attempts to contact them failed. I ended up somewhat crashing (well, I did wrangle a late invite for a brief presentation) at which I presented data, including some which indicated AOL's little problem. Their chief postmaster was present. We talked a bit.
More recently, Yahoo have had issues in severely restricting mail delivery rates to Yahoo's MXs, even for long-existing, SPF/DKIM compliant MTAs. I'd gone endless rounds with their helpdesk and had repeatedly emailed (with no response) their CTO. So I sent a group email to a roster of their top (C-level and senior VP) staff, again with some data indicating issues (pflogsumm delivery stats showing hours of delay) and an introductory text "Gentlemen, you have a problem". That finally got a response in the form of a "Yahoo concierge" who spoke with me a couple of times and sorted the problem (and also promised a review of policies in general, in case anyone else is having issues).
Just a few anecdotes of different ways to get a company's attention. There's no one-size-fits-all approach, so be flexible. I generally try a direct private contact first, but ... well, if that doesn't work, I've got a bag of tricks I can pull out. Public shaming can work, but I'm willing to give the benefit of doubt first.
Look forward to an explaination?... then contact them directly instead of "sand bagging" them (borrowing a colloquialism from Family Guy).
