I flunked in my first SCJP exam so bought another voucher. But within 2 weeks I got a mail from sun that I'm eligible for another chance on my first flunked exam as part of a promotion. Now I want to return the voucher I bought. Any help or information?? I mailed Sun and they replied back to me. They got the necessary details from me but after that they didnt reply back to any of my mails. Any idea?? Please help. I dont want to waste my money.
