My account was hacked and I can’t get past the security questions

Secure the email account linked to the account first: change its password, enable two-factor authentication, and check for unfamiliar recovery addresses or forwarding rules. Also review saved payment methods and signed-in devices, and remove anything you don’t recognize.

Try the provider’s official account-recovery process from a trusted device or browser. If you’re still signed in on a current device, check the account settings to see whether you can add two-factor authentication or a trusted phone number. Don’t keep guessing the security answers, since that may trigger additional lockouts.

This sounds like an older account that still relies on security questions instead of modern two-factor authentication. If the attacker changed those questions and you aren’t signed in on a trusted device, recovery may be difficult. Contact official support through the provider’s account-recovery channels and be ready to verify ownership with billing or account information.
