Not all customer service is bad...
I've seen many blog posts by people where they completely flame the customer support provided by a company like Dell, HP, Sony, Best Buy, etc. Well, I had a very good customer service experience today so I though, to be fair, I should share the other side of the story.
One of my LCD's at home (a 21" Samsung SyncMaster) started displaying some very thin (1 to 2 pixels wide) lines (about 7 or 8 of them) that ran vertically across my screen (from the very bottom to the very top). I paid pretty good money for this LCD so I wasn't about to just let this problem remain. So I called up Samsung's customer support and after providing a little personal information the Samsung rep gave me some troubleshooting steps to take in order to ensure it wasn't the DVI cable or the video card which, it wasn't. After that, things couldn't have been easier.
Since my LCD was still under warranty (3 years, parts & labor) Samsung is going to send me a replacement LCD, and they're paying for the shipping on the defective one I'll be sending back to them. 7 to 14 business days and I'll be back on a brand new LCD. Thanks Samsung!
