I need to access an old iCloud account and I can’t wait 13 days to to be able to access it. Can anyone help?

I presume you are referring to account recovery? --> How to use account recovery when you can’t reset your Apple ID password - Apple Support

"In some cases, you might be able to speed up the account recovery process or reset your password immediately by verifying a six-digit code sent to your primary email address. You might also be able to shorten the wait time by providing credit-card details to confirm your identity. If you’re given this option, an authorization request goes to the card issuer."

No, this cannot go faster, you will need to have to wait until the account recovery process is complete
