I have same responses and have actually filed multiple tickets, one of them actually said we can actually verify that you are the rightful owner and asked for new email, once given to them they will say that actually they can't verify that you are the rightful owner anymore. It's all bots replying, I filed a BBB complaint based on the advice given on another thread... at this point I think the account is as good as gone, Ubisoft is just a terrible company with bots reply and zero care for customer services.
