Welcome to the Q&A Forum

For a while, Google has been auto-appending brand names (or their best guess) in that "Title Goes Here - Brand" style, even when "- Brand" isn't in the title tag. There's no way to tell them not to do that, unfortunately. When they launched the redesign to the wider column, it seems like title rewriting increased, IMO. So, the weird question here, clearly, is why does Google think your company is called "0 Reviews"? It could be an old legacy bit of bad data somewhere, like DMOZ (as Russ said), or it could be something they're seeing on-page or in inbound anchor text. Unfortunately, without being able to see the site, this kind of thing is really tough to diagnosis.
