account linking Apex Legends

So for starters here's some information. I have an Apex account on PC that I'd like to use on PS5 since cross progression was added and I recently got a PS5, but when I tried to link my PS5 account to the pc one I was meet with "your account is already linked to: SSQUAD_FeedBack" or something of the sort. No clue who or what this is btw . So I unlink it. Simple right? Nope. Even after unlink my PC account from the other one it still says it's linked to another and can't be linked. May I requested my account be unlinked manually from any and all PS accounts? That way I can link it with the account I actually wait to.
