I recently paid for Dell's next day service with a new PC purchase.
The PC arrived broken, and Dell refused to send anyone out to fix it.
Instead, I waited weeks for a replacement, feeling like a chump.
When I complained to Dell, none of their employees seemed to understand that they had failed to honor their warranty, or why I would be disappointed.
The replacement machine works fine, but Dell violated their agreement with me and so I can no longer recommend them.
