I got served an 816 as a result of a mistake on mine and my banks part, someone stole my card information and I asked my bank to dispute the wrong fraud cases, resulting in my legit, 45 dollar AC purchase to be reversed, a steam restriction and a 816. As soon as I realized I called to reverse my dispute, but the damage was already done. I have since sent a ticket to both SEGA and PSO2, I have received an email from PSO2 about said issue, stating they would look into it, and they acknowledged the problem, so I hope that an actual human saw it. Heres hoping, I'll update as things happen.

got my account back 🙂

That was fast. Glad you got it worked out! 🙂
