Account Stolen, Support won't help. Looking for advice.

So recently my account got stolen, i had no idea how until i checked HaveIBeenPwned.
Bit of backstory is necesarry, i was lik 13 when i made this account back when they didn't check if your e-mail was real, so yeah i couldn't send my support message from my orginal mail because it was something like [email protected], before eventually realizing i should switch it to my actual mail. Anyway i still tried to contact support because i feel like i could present good evidence, that being the following;

1. i can present e-mails from 8 years ago regarding my account on the e-mail i contact them with
2. i can give them my password prior to being hacked
3. according to my e-mails they logged in from 4 different locations from the globe, within 15 minutes, (Brazil, UK and US) then they changed my password and e-mail, and suddenly the next day i try to reach them from my previous e-mail.

My question now is a simple one. Do i keep bothering support in the hopes i'll get my account back or do i simply cut my losses, learn my lessons about that i should really use MFA in this day and age, and just make a new account.
