This is a user to user forum, people like you helping other people. Apple only reads posts to moderate them, not to provide support.
We see posts like yours several times per week. It is an unfortunate situation but according to various posts, Apple may permanently lock accounts for various reasons (very broadly outlined in section VII-B of Legal - iCloud - Apple ). If it isn’t apparent that is what has happened, you can contact Apple and ask if that is the situation, but don’t expect them to tell you why. You, or somebody who has managed to get access to your account, are likely doing something Apple is interpreting as account misuse. You will have to see if your activities could be construed—rightly or wrongly—as meeting any of Apple's conditions in the legal article. You will need to create a new account and stop doing things the way you have been that may have caused the other account to be locked.
In this situation you may be able to still use your equipment with a new account or even no account at all. Apple can completely reset a device if a person can provide sufficient evidence of valid ownership. Check the requirements and steps at: Activation Lock support request - https://al-support.apple.com/#/additional-support Apple says, "Proof of ownership documentation is required," but does not detail what currently constitutes proof other than it “must include the product serial number, IMEI or MEID.” Apple may typically require the original receipt* issued by Apple or an Apple Authorized Reseller. If Apple resets the device this will give you access to the device but won't restore access to the account used to lock it. There is nothing that can be done to expedite an Activation Lock request.

Your question is not the one being addressed in this thread and it would be better in future if you would start a new topic if you have a question. That way we could focus on just your issue and people won't get confused by two different sets of solutions being proposed.
