If it's a
legitimate complaint, the BBB is a good place to visit. Otherwise, you can leave reviews on cnet, Newegg's product page, and most sites that do reviews have a user comment section. Heck, you've got some decent video editing software - use it to post a video review on Youtube or your service of choice.
Keep in mind that if people do not agree with your opinions, many of these venues are unmoderated, or at least lightly moderated - you
will be flamed.
The advantage of a moderated forum like this one is that you can voice your concerns in a friendly, pleasant manner (mostly) without fear of emotional damage from trolls.
The community here seems great, and from the perusing that I have done since purchasing (quite satisfied so far, by the way) in these forums, I don't see any heavy handed banhammering or crazy censorship of people's legitimate issues.
Hope you get your issues settled, good luck.
Edit: If you have the patience for it, you could go to reddit as well.
