Hi, this is a community forum and probably none here has access to the information required to confirm your issue. I would recommend you to insist through the official channels you mentioned until you receive an answer.
I have made the payment for OCP voucher in india through oracle university. It's been 5 days money was debited but, still I have not received any confirmation mail or voucher. I tried calling local customer care number and sent multiple mails but no reply from them. I even raised the ticket but no one has replied on that. For OCA I received voucher with in one day after payment but, don't know why it is taking so long for OCP voucher. I was hoping some one here could help me.
