Need to find the email linked to an X account

Hi, thanks for answering but i am 100% sure someone here can help me. I’m really desperate trying to get that account back, i have important dms, followers, accounts i follow, groups i’m in and friends on that account that i’ve had for years and that i need to get back. I’ve sent dozens of emails, claims, made new accounts trying to get help but no one has replied from X. I really need to get this account back and I’m willing to give a reward if needed.
