I got the same auto reply about the policy. I can understand the policy if it was a regular sigil or commendations that I wasted but this is something that there is not another way to obtain one in game. Turbine is applying a standard policy to a special situation and all it is doing is disappointing people in what should be a celebration. There is no reason they couldn't correct the error as it is not going to affect game play at all.
I can definitely take some responsibility because I was rushing and did not read the description carefully enough. However, the blame also falls on Turbine because the system is flawed. Either make it so that you cannot purchase skins, traits, etc outside your class or have separate trainers by class and not by race. In the freep world, you are not going to a dwarf, elf, hobbit, or man trainer. You are going to a class trainer and the same should be on creep side.
