<Re-Titled by Host>
If it's for a limited period of time you should have got a message saying how long. If you've disabled your account try : If your Apple ID is locked - Apple Support
To reset your questions : If you forgot the answers to your Apple ID security questions
If you don't have a rescue email address (you won't be able to add one until you can answer your questions) you will have to contact Support in the country where you are (and which is therefore the country on your account) to get the questions reset - from the above link :
If you can't reset your security questions
If you can't send a reset email, don't have a rescue email address, or can't access email at your rescue email address, call us for help. When you call, you might need to create a temporary support PIN to verify your identity. After you reset your security questions, you might want to update your rescue email address.
If your country isn't on that ‘call us for help’ page then try this form to contact Support : https://www.apple.com/emea/support/itunes/contact.html
When they've been reset, and if you don't already have a rescue email address, you can then add one for potential future use : About your Apple ID email addresses - Apple Support
Or if it's available in your country you could change to 2-step verification : Frequently asked questions about two-step verification for Apple ID
