You can reset your Apple ID security questions when you follow these steps.

Security questions help Apple verify that you're the person requesting access to your account. Use the steps below to see if you can reset your security questions using your rescue email address. If you don't have a rescue email address on file with your Apple ID, contact Apple Support.

Reset your security questions

1. Sign in to your Apple ID account page.
2. In the Security section, click Change Questions.
3. When you're asked to answer your security questions, click "Reset your security questions." We'll email you at your rescue email address. If you don't see "Reset your security questions," you don't have a rescue email address and you need to call us for help.
4. Follow the steps in the email to set up new questions and answers. Didn't get the email?

If you have trouble remembering your security questions, you might want to set up two-step verification. With two-step verification, you don't need security questions to secure your account or verify your identity.

You can also secure your account with two-factor authentication when it's available for your Apple ID.

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 you answer your security questions incorrectly too many times in a row, you temporarily can't access your account. You can try to reset your questions after the waiting period ends.

I Don't know if this will work. I tapped on Brazil and got to here.

You can swipe down to change to English. Give this a try. I'm sorry, I know this is frustrating, but trying to find an email address for this is getting me nowhere.

I have tried reaching out in another forum where higher level users have access, to see if anybody can offer any suggestions for you. I am totally at a loss now. Hang in there and hopefully someone will have another idea and will chime in here to help.

You could try this form to contact Support and explain that you are in Guyana and only speak English, and not Spanish and Portuguese, and hopefully they'll give you a sensible reply : https://ssl.apple.com/emea/support/itunes/contact.html
