[2023] Banned after 2-step authentication was disabled

My phone was broken months ago, so I asked Ubisoft support to disable 2-step authentication for me.
I did not reactivate 2-step authentication and a week later r6s told me my account was permanently banned.
My account was 7 years old and I do not use cheats in games.

I contacted battleye, they didn't answer me. Though the ban was not informed by battleye.
Ubisoft support just told me they won't unban me.

A player is banned because he disabled 2-step authentication.
I have my share of responsibility but this case is too obvious.

7 years old clean account > disable 2-step authentication > "caught cheating" > permanent banned

Punishing cheaters is good but how can you tell if the player is hacked?

I am not 100% sure whether my account was hacked or not.
If that was not the case then I don't know why this happened.
I have just played one game after disabling 2-step authentication, to check if I can login and play the game.
I didn't even play the game after that and one week later I was banned.

Ubisoft team don't have measure to handle this kind of situation.
Please unban my account.
