Woke me in the middle of the night. No idea what time, my phone rang 3 times. Cost me about an hours worth of sleep that I needed dearly. My phone lets me block the number so I did. my guess is they are collecting a list of active numbers that they can use in the future or sell.
I just had a call from the number. 11:04AM Mountain time. I'm at work so didn't answer and I don't know how many times it rang. They BETTER NOT call me in the middle of the night like so many others have reported!
