Registration Code not working for Sims3.com or Origin

I just bought Showtime from Origin a few days ago and my code didn't work. I used the Live Chat feature and, after more than an hour wait, finally talked with someone who, after checking and taking up another 15 minutes or so, was able to give me a registration code that worked. The codes for the extra content worked fine and I didn't have to do anything with them. The wait isn't usually this crazy but I'm guessing that, with the big sale Origin had this weekend, there were a lot of similar issues.
