Who called from 9372030967

Called but didn't leave a message. When I called it back, it just rang and no one ever answered.

When you see that number, I do not understand why you answer the phone.  WHY  - WHY  -

Just called my unlisted phone which is on the do not call list.  I answered, no one says anything.

Locked my phone out for 4 minutes of dead air. Couldn't make the answering machine or any phones hang up. Called back and three times and repeated the process.

No message left on answering machine.
