I also got a call from this goof ball.  No message left, just a hang up, on the answering machine.  You know if they aren't leaving messages, it could be one of 3 things.

(1) He's trying to sell you something and won't leave a message, because he/she figures you'll ignore and not return the phone call.  Well...yeah lol.

(2) He's not quite right in the head

(3) He's dyslexic, refer to 2.

Neither of these are good options for us, if it persists, call the police and see if they have suggestions.  After all, your service provider could be obliged to cough up phone records, if demanded by court order.  

The problem with these sales creeps, is that they give a worse impression by not leaving a message.

they just called me offering to clean my air ducks...... I live in an apartment

This number called us today and I called back to see who it was. After saying to stop calling us they have continued to called about 10 times.
