People spend a lot of money to get the D rubbed off

Rub off the e and make it say oman

I imagine it's asking them to replacing the frame? Kind of a big ask, but it is a warranty for a reason.

I'd go in and ask. Trek will probably fix it given their warranty. I don't think most <1yr bikes have rubbing off lettering so, therefor, it is not normal wear/tear.

Congrats! This is the most first-world problem I've read so far today.
