I won a week ago today (Sunday). I waited patently for the email to come. It didn't come Sunday, or Monday, or Tuesday. So on Tuesday, I sent an email to
winner@prizelogic.com asking if they needed anything from me. I received a response later that day that they would need the verification code that popped up when I won, and that the code should also have been in the confirmation email (that I never got). Luckily, I had printed the confirmation code. They also suggested I check my spam folder to see if it was filtered out mistakenly (which I had already checked). They told me just to hold tight, and I would receive documents in the mail in Mid-January to sign and get back to them.
This was a bigger prize than a pin, though, so I'm not sure if you would need a code.
I'm trying to be patient, but patience can be a weakness of mine.
