Hello gugabe,
If you can't send a reset security questions email, please contact Apple Support as shown below.
If you couldn't send a reset email, don't have a rescue email address, or can't access email at your rescue email address, contact Apple Support. Apple may ask you to generate 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 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.
If you forgot the answers to your Apple ID security questions - Apple Support
Thanks for using the Apple Support Communities!
Cheers,
Alex H.
