I’ve lost my account, and I have already sent my information to fgo support email, but I heard they are slow and I really want to play again. If there anyone kind enough to give me a old account or 2nd account they don’t use much anymore, I would be extremely grateful not playing has impacted me greatly.
Make an alt, or a JP account… or find something else to play. You’ll be fine waiting another few days, if that.
You´ll have better luck asking here.
Hope you get your original acc back.
