I had the very same problem but in all honesty it was my own fault for not checking my mails and starting on a new character because I wanted a fresh start. So all my new characters do not have the legacy mark and I deletet my legacy chars after some time because I did not plan to play them anyway. Today I regret doing so but oh well. My actions, my fault. I can not blame SE for it. To cheer you up I can only tell you that you are not missing out on much. Having a tattoo you can barely see is not something I am very attached to. Learn out of yor mistakes as myself and keep an eye on your accounts be it game accounts or other things.

@ legacy topic: The legacy chocobo is account wide as far as I know but the tattoo is not since it is linked to the calamity. To get legacy status, the chocobo and the sub discount for ARR you had to sub for a certain time before the servers of 1.0 shut down. Sadly I quit after few month after the 1.0 launch and did not qualify for legacy either. ;_; Again... my fault.
