I sold 370 Recycle Badge to NPC while clearing storage and found out 3 days later...

Every MMO that I have played until now had customer support for a case like this. I did similar stupid things in literally any MMO and the support was always able to help, did you already contact them?

You were dumb and didn't pay attention to what you were doing. Why would support have any reason to do something here?

@Right-Hand-From-Behind Good thing that's not up to you.
