no message left, no idea who called
Have no idea. Just saw a missed call. No message. Have seen this number before. Keep reporting it to the do not call list.
Rang, but left no message. This is an auto dialer looking for "live numbers". If you answer, you will get a call from a telemarketer within 15 minutes as they know they have a "live number".
Rang once and hung up... WTF!
