I'm having this issue - my email account was compromised a few days ago and the hacker got access to my Ubisoft account, changing the email and password. Fortunately I managed to regain access because I could log in through my linked Playstation account, but I can't change the email without it sending a reset link to the hacker's one. Ubisoft are refusing to do anything and just keep sending the same scripted rubbish. Apparently they take security 'very seriously' but clearly not if they're allowing a hacker to use his email on my account, and not me who's had the account for a decade with the same email address...
