My lockbox was replaced!

[Jack Forester]

I bought a SFR on 9/10. I've had guys out to quote work. Today, the termite guy is at the house telling me the lockbox code is not working. I haven't given the code to anyone else, so I ask if he is sure he's at the right house. He sends me a photo of the house. It's the right house. He sends a photo of the lockbox. It's not mine! Turns out there is an "Attention!" sticker on the door warning not to turn on any breakers or water. The prior owner's mortgage company "secured the property", even though we closed a week ago. Working with Safeguard to get back into MY property. Has this happened to anyone here? Do I have any recourse for lost days of rehav/rent?
