Same setup with me. No ringing from the call just a voice mail from Miss Sanders and a reference # towards some concerns with an electric bill. I just deleted the message.
Number initially came up as unknown, didn't even go to one full ring before it went into "Missed Calls" they left a voicemail, which is how I was able to get the number. Voicemail was from a very young sounding girl who identified herself as "Miss Sanders" calling about important surprise charges on my electric bill. Never gave my name or what company she is calling from. Given I live in Missouri and use a local company and have no surprise charges on my utility bill this month, I am fairly certain she is fishing for information. Beware of caller.
