Who called from 2057032872

Bscene timea of day. 5am. When I called the number back the message said, "to call this number you sneed to register this number with BB Harmonys Secure Call Service"

We get calls from this number about once a week at work.  No one is on the line.  The line just stays open if you wait for someone to say something.

Received call on new iPhone. No one answered. Have several calls in a day from different numbers but no one answers

Exact same thing is happening to me. Out of state calls 2-8 times per day for the last 2 weeks. They even call at 3 and 4 am! No one is ever on the line.

Got a call at 3:56am from 205-703-2872. When I called it this morning the message said I had to register my number with E Harmony secure call service. What the hell???
