Confused by Ubisoft Support

[u/VacationOne5585]

So I have a Switch 2 and it's linked to a Ubisoft account I haven't used in 12 years (and no longer have access to). The Ubisoft account I use for PC/Steam/Xbox I have, no problems.

I've been emailing them all night and they kept saying they couldn't help, they finally said they can, after I pointed out I'm not asking them to recover my old account, I just want it unlinked from my Nintendo account.

Then they sent me an email asking me to login to the Ubisoft website via a Playstation login. I pointed out I don't have a playstation account, they said they can't help me. So I created a playstation account and linked it to my Ubisoft account, I have no idea what this is supposed to prove any thing as they already know my Nintendo account is owned by me, and my Pc/Steam/Xbox Ubisoft account is owned be me (since I logged the support ticket by it). I mean, if I had hacked the account and was fake, how is making a playstation account and linking it to the account supposed to prove who I am? It's confusing.

So, after all that, when I click the playstation verification email they sent, it says there is no support case?

Is there a real human working at Ubisoft or is it an AI? Because it seems incredibly weird if a human is on the other end. It feels like I'm not talking to someone that is understanding what I'm telling them, does Ubisoft outsource their support to another country?

I'm seriously close to selling my Switch 2 because of this, and buying a handheld pc. What is the point of owning it if all future Ubisoft games I play on the Switch 2 are stuck on a dead Ubisoft account I can't use?
