You're right, if you've paid for a product, you have a right to have it serviced if not working properly. Unfortunately, we have developed a tendency to believe that everything should happen at a blinding speed, like our systems work, in comparison to the plumber, who works on an emergent basis for an emergency case. I'm not sure how much of an emergency you're in, if you're planning on giving a presentation or producing work and need those icons, then you should ask for and receive appropriate time responsiveness.
December 11, 2006, however, is far too long to wait without any kind of official statement as to status. If it has gone this long, you may want to do some digging around and take the route of breaking out the real paper and taking them to task.
If you anticipate becoming economically damaged in some way, you should probably notify them of that fact.
Good luck.
