Business card left on my car last night, "Please contact us ASAP" with the phone number. Why would someone come inside my property and leave a note?

My father in law just found the business card on my screen door when he came back from the store, it wasn't on there when he left the first time and me and my husband have been in the living room all night with the lights on watching tv and nobody knocked on the door. Call the law if you receive the card on your door it could be a scam.

I found this card Please Contact Us ASAP with a ref # at 5:46am this morning, turned backward on the driver side window.  It had to be placed there between 9pm and 5:30am.  I called the number blocking my number at 6:00am and got an auto generate voicemail.  I live in a gate community so this is rather strange to say the least.... I didn't call back during the hours indicated on the card.

HORRIBLE
