I actually work for the Herff Jones yearbook division. Your experience is unfortunate, but you must remember that everyone makes mistakes. We make thousands and thousands and thousands of rings each year so some are bound to have mistakes. There are so many hands that go into making each product that human error will happen from time to time -- with any company and any product. I know that customer satisfaction is a priority for us, so I'm sure the rep you were dealing with is doing all he or she can to get the product returned to you as ordered. As for the time factor, these rings are a custom product and take time to make.
I wouldn't speak so highly of Herff Jones if I didn't believe in it so much (nor would I work for them!). In fact, we make the national championship rings, the Heisman Trophy, the Stanley Cup, the Indy 500 trophy and the US Supreme Court Justice robes -- so we must be doing SOMETHING right!
If you continue to have trouble (and I can't imagine that you will), feel free to contact me via this message board and I will find someone in that division who can help you.
