As of Tuesday, I've been promised a refund by the people at Nissan. They said that I can expect a check within 6-8 weeks. However, it was only after 4 unsuccesful calls that all ended with a promise of an email explaining my options which never came. I was one of the people prevented from ever entering the parking lot, so I don't know if that made a difference. During the last phone call, they asked questions about that. I'm glad they're (finally) doing the right thing.
