Has anyone had a Netflix stolen from you?

Firstly, I have a game plan it place of what to do. Getting a new one isn’t the problem. I’ll call Netlix and they’ll fix it. I am peeved that it was the first disc in a series, but whatever.

Here’s what happened; I got home from a long day at school and was looking forward to watching it. My sister hands me the mail and there’s two that are still sealed and one of those throw-away sheets that come with it with the sticker seal. I’m confused. That’s all that was in the mail. When I open the mailers, I don’t peel the sticker off of one side and put it back, like this one was.
I’m really irritated right now and I’d appreciate some jellies giving me some comforting words. I’ve found stories online about postal workers stealing movies from Netflix. But, has anyone had any personal stories about this happening? It’d make me calmer.
