A bit pissed at Google Places.

Many moons ago, my business applied to Google Places. We used our company PO BOX as the address.

It was accepted and was successful for us.

Somehow, they changed their rules and suspended the account, without actually telling anyone about the change in rules.

Google, you suck.

That's very poor customer service and is rather akin to a dictatorship. You could at least tell someone that there is a change in rules and ask that the information is updated rather than summarily cutting a business off.
