Hm for me its been years, i once lost my old old account by logging in on a new phone and my english was never that great especially back then so it said transfair the noob character on the email or the email character on the noob character. Basically both options were transfair so i pressed that and it replaced my email character with a brand new one. I tried the toonslab support in 2018 a lot but it went nowhere they dont seem to even speak english or they send random troll text prefixes. Admins in-game said to go to the support page since its not their role to manage accounts.

(I dont know if there is still hope in getting access to an account that has ben lost and maybe deleted 4 years ago but would be amazing)
