Hello,
I'm sorry, but I do not understand the issue. Are you, perhaps, saying you have received an email containing a confirmation request to a different email address? This is how I understood your message.
Also, the email you partially screenshotted also says you have 7 days to claim your prize. It does not say you are delayed, I wager.
It would probably be best to forward your message to colleagues who take care of the tournaments.
I'm assuming they will get in touch with you.
