My Developer Account cannot be activated because I used a relative's credit card
From the iOS Developer Program Support:


  If I enroll as an Individual in the Standard program can I use someone else’s credit card to purchase the Program?
  
  The billing information provided for
  the purchase must exactly match the
  Program enrollment information. If
  this information does not match your
  enrollment will be delayed and you
  will be asked to provide a notarized
  copy of a government issued
  identification.


I would contact support and ask them what to do next.
