They tried looking it up by my name, my phone number, my e-mail address, and my mailing address to no avail earlier in the day.
I called them back to follow up, and got the nastiest cast member I have ever encountered (she was so downright rude to me and I was so shocked that I forgot her name and didn't even think to ask her what her name was). She called guest services, and said, "You need to understand that it can take 24 to 48 hours for the pin code to be downloaded." I said to her that I can't understand that, and that if Disney sends me an e-mail with a pin, it should be valid when I get it. She said that there's a problem with mine, and went on to tell me how she has been booking people with pins without a problem all day (she was really pissy and sarcastic about it--I felt like she was trying to pour salt on the wounds so to speak). I told her I knew that, and that I knew of many people who got their e-mails the same time as me and their pins worked fine.
Before I hung up, I told her that I hope they realize they have a very disappointed and frustrated repeat guest, and she says, "That's too bad" really sarcastically.
I'm going to call back again when I get home, and ask to speak to a manager. I know that they log information on calls, and I'm goign to tell them how downright rude this woman was to me.
