apple ID device enrolment program

Hello there,

he got finally approved by apple for the device enrolment program.

now if got the problem that i can't use two-step authentication because i don't know the answers to the questions.

after multiple calls to apple in the Netherlands and in England, i got the answer that the can't help me and i need to make a new id. this is not a problem, but adding it so that i can log in on https://deploy.apple.com/ is.

so, in short, can somebody explain to me how i or apple can change the apple id that is currently attached to the Device enrolment program?
