If I may... I kind of agree with Moi.
I understand both sides. For Alice it may look ugly, but Luna is a bit pushy about the matter. Just drop it guys.
Alice has the right to deny her service to anyone. And Luna, I don't think a mod has any power in this matter, it's a conflict between you two. The only thing a mod may possibly do (I'm not sure though, I mean they are pretty busy too) is to show a proof to Alice that you used the FC you bought from her according to its purpose and that afterwards you obtained more FCs of your own. But still Alice will keep her right to decline to you, even having the proof, because her other argument against it is how high a price you put for the FC on the market, which she deemed unfair to other users.
I don't think it's really worth all the nerves you two are wasting here
