My Ubisoft Account Was Compromised By Hackers

A hacker took over my Ubisoft account and changed the email address that was linked to it. I sent in a lot of support requests with good proof, but I haven't heard back from a human person—only automated replies from bots. I even gave a screenshot of the game's purchase date and all the details from my associated Steam account, but nothing has been done to fix the problem. Even though I've tried everything, the account is still with someone else. I felt like my position didn't matter because I went through this process and didn't go anywhere. I just want my account back safely. I truly hope Ubisoft takes this seriously and stops disregarding cases like mine.
