Inactive forever Apple ID

This seems lame, but have your considered these possibilities:

See this Apple document If you see a message that says 'Your account has been disabled in the App Store and iTunes' https://support.apple.com/en-us/HT208856" There might be a problem with the payment method that you have on file. When you see the message, don't try to edit any of your account information. Instead, contact Apple Support for help.”

Use the support link above.

And, if necessary, go here is how to contact iTunes worldwide support via text or chat using this link https://support.apple.com/choose-country-region/itunes After choosing your country, see the heading Tell us how we can help.

See this document If your Apple ID is locked or disabled https://support.apple.com/en-us/HT204106 "If you or someone else enters your password, security questions, or other account information incorrectly too many times, your Apple ID automatically locks to protect your security and you can't sign in to any Apple services.”

__________

See If you forgot the passcode for your iPhone, iPad, or iPod touch, or your device is disabled  https://support.apple.com/en-us/HT204306, especially the section entitled Remove your passcode. 

If you don't have a computer as mentioned in Remove your passcode, then "borrow one from a friend, or go to an Apple Retail Store or Apple Authorized Service Provider." Of course the last option usually is not available now.

Later the document says: "If you can't update or restore your device using recovery mode, or you can't use recovery mode because of broken or stuck buttons, contact Apple Support. Then follow the steps to set up service for your iPhone, iPad, or iPod touch."

Are you seeing activation lock?

See Turn off Activation Lock https://support.apple.com/en-us/HT201441See this heading If you erased your own device "If you don't sign out of iCloud before you put your device in recovery mode and restore, it might remain in Activation Lock. That means you need to enter the same Apple ID and password that you used when you previously set up the device." 

See: If you forgot your Apple ID  https://support.apple.com/en-us/HT201354  and

If you forgot your Apple ID password https://support.apple.com/en-us/HT201487

You also can use Having trouble signing in/iForgot

 https://iforgot.apple.com/password/verify/appleid to identify either or both

If the above information does not work for you, then see below.

Ignoring extenuating circumstances, activation lock can be turned off only by entering the correct Apple ID/password combination. The correct combination is in the one used in setting the device up prior to activation lock being enabled. Note that there is no way we can help you to systematically recover the pertinent Apple ID password.

Thus, we will not be able to do anything for you except to mention that Apple Support may be willing to help you if you have an extenuating circumstance (e.g., you have the receipt for your purchase of the device with its serial number on it or a court order instructing Apple to assist in the provision of access to a decedent’s information from the deceased person's accounts). See How to request access to a deceased family member's Apple accounts https://support.apple.com/en-us/HT208510.

So, if you think you have an extenuating circumstance, even one not mentioned above, you can contact Apple support for help with your problem using these options:

I see. It looks like the problem is that you have no receipt with serial number on it. I am sorry about your problem. I mentioned above:

So, if you think you have an extenuating circumstance, even one not mentioned above, you can contact Apple support for help with your problem ,,,,

But, it looks like you have done that. After all you have been through, do you have any idea why your account keeps getting locked? Or what Apple did twice to unlock it.

Did you ever erase the device without signing out of iCloud first?

What a mess! Please understand that the support people that post here are not authorized to do anything about fixing your activation problem. For the most part, we are Apple users like you helping Apple users. Be safe.

You are very welcome. Be safe.
