Allot. Google places is a disaster. Not only are the listings a problem, but the reviews are badly broken. I saw one case where a woman wrote 25 restaurant reviews in less than 24 hour's. Someday they may clear this up. But for now reviews and the problems you stated are costing businesses lots of money.
And Google expects them to sit back and take it. There's no tech support, although you can post a message on their board, and every SEO(?) in the world can see who you are. And all these people from India call you and want to solve your Google places problems.
It's hard to imagine a big company could screw this up this bad.
