Yes, that sounds incredibly annoying. However, mistakes happen. The SA who called you to tell you when the shipment would come in probably neglected to remove your name from the wait list after you told her you were no longer interested. Most likely just a case of human error. We all make mistakes sometimes. I would definitely call to professionally complain though. And when I say "professionally", I mean to do it in a polite but firm manner. You'll probably get much farther that way.
Sorry for your troubles and I hope that it gets resolved for you soon!
