Unable to Erase Mac Due to Deactivated Apple ID

That old Mac is bricked. It cannot be used, or reset.

Deactivation or deletion must be the last step, as it bricks everything associated with.

You’ll need to reactivate the Apple Account (if you deactivated, and did not delete) and reset, or present proof of original purchase such as a receipt from Apple or an authorized reseller, and get the ownership relocated.

As for getting help here, this is a user-to-user forum. We can’t resolve this. Apple may or may not read posts around here, and very seldom replies.

The Mac is not necessarily "bricked" if you can successfully do either of the things I suggested.

Are you using the correct term?

You requested an account be deactivated and now want it activated again: click on this link about 'How to deactivate your Apple ID account' --> How to deactivate your Apple Account - Apple Support

For information about how to delete an Apple Account (formerly “Apple ID”), read this support article —> How to delete your Apple Account - Apple Support

Carefully and thoroughly read that article for information about what happens when you delete your Apple Account. For example:

"Make sure that you sign out of all your devices to avoid issues with apps that use your Apple Account or iCloud. After your account is deleted, you can’t sign out of iCloud or turn off Find My iPhone Activation Lock on your devices. If you forget to sign out, you might not be able to use your device when your account is deleted."

You could try to get the account working again, as outlined in: How to delete your Apple Account - Apple Support

"What happens if I change my mind after I have requested that my account be deleted?

While your request is being processed, you can contact Apple Support [call them at a telephone number for your country --> Contact Apple Support - Apple Support ] with the unique alphanumeric access code you received, and we’ll help you cancel your request. After your account is deleted, Apple can't cancel the request, reopen your account, or restore your data."

Alternatively, Apple can reset a device if a person can provide sufficient evidence of valid ownership (usually the original receipt from Apple or an authorized retailer —> Keep your receipt after you buy an Apple device - Apple Support ).
