My question is this behavior expected or have I missed anything? I was expecting to make the payment with my card and get the voucher right away, which was not the case.
If the above is the correct behavior, then how many days would it take the get the email from oracle and what would be the payment method?
It seems odd, but you might want to have a Live Chat with the Oracle people and find out if it is correct (check their Certification site to find the link).
And just for info, the validity of the voucher is now 6 months as shown in the oracle site.
Yes, I have just seen they updated all vouchers to a validity 6 months!
