Cannot unlink from deleted email and unable to contact support

Hello,

I am unable to link my current email with my Steam account due to it already being linked to an email that I deleted a year ago. I have tried creating a new account, foolishly thinking that it would help me, but now I have hit this wall. 

To show proof, I can provide a screenshot of some of my Steam purchases in 2022 and 2023. These purchases were for Apex Legends and Sims 4. In fact, I can also provide the password I used for the old account as I still have it saved. 

I have tried to submit a ticket nearly 3 times now, following the steps to the letter, but a ticket was never submitted. I say this because my 'My Cases' page still says that I have never created any. Additionally, live advisors are not able to handle these types of cases, apparently, when I tried to contact live support. Later, I saw responses from community managers in these forums prior to reach out via the [edit: email address removed] email directly. Unfortunately, this has also become a dead-end with no response. 

Thus, I am posting this here now. Until I can get this resolved, I cannot play any EA related games as I am unable to accept the terms and conditions. Unfortunately, to do so requires signing in first, which as I have hopefully made clear by now, I am entirely unable to do. 

Thank you for any help,
TaskingMyManager
