Hello,
since the beginning of May, I try to contact with ISC2, however didn't yet get the response on email or live chat - I would like to purchase CISSP voucher. My university is paying for the exam and I need an invoice. How should I proceed with that? I remember some time ago it was managed by Pearson Vue, however now I think it has changed? Can I pay for the voucher and then at the comfortable time, choose a date or I need to do it just after purchasing the voucher?
