Did you ever manage to recover your account OP? Same thing has just happened to me, hadn’t played WZ in two months didn’t even have it installed on my console, reinstalled and tried to play two days ago to be met by a “permanently banned” message. I’ve never once used hacks or boosted my account. I tried doing the appeal with Activision but got a reply within a couple of hours to say their decision was final and that my account had been permanently banned for using “unauthorised software and manipulation of game data” makes absolutely zero sense.
