My cell phone didn't ring but I got a voice message from this number. Google voice translated it to text as follows:
"Hey, it's Katie waterville Express. I was just calling to let you know that I'm about 5 minutes away. 1 if you want to give me a call back my number is 619 792 5020 if not, I'll see you soon. Bye."
I have no idea who this is and needless to say no one showed up 5 minutes later. Strange.
