Complaining about a product or service to your neighbor is easy, but did you know how easy it is to send your complaints (and praise) directly to the company itself? Thanks to Planet Feedback, you don't have to waste time looking for the corporate address. Planet Feedback will make sure that your comments reach their target so that all you have to do is make one easy visit to their site. If the company you're looking for isn't in their extensive database, you can still use their site to coach you through the letter-writing process; then, print your letter and mail it to the company the old-fashioned way.
