Blockbuster receives DVD back I never got.

Today in my email I have 2 messages from Blockbuster.com

1st email is for the DVD that I had the problems with 2 days ago.
They have now received it.

2nd email is for a DVD they have received back from me that I never got myself (when I was a customer).
Let me elaborate.
I had in my “queue” The Doors (by Oliver Stone).
NEVER got it in the mail. I reported that I never received it and they sent me the next movie in my list. So I never got The Doors movie but yet I just received an email that they got it back. Weird.
