Just called my cell, did not leave a voicemail

Unknown caller. I have lost my job and have been applying online to find jobs, mainly because most employers want a resume submitted online. It is frustrating that because of this, I am now getting multiple daily solicitations from unknown callers, and multiple callers from various area codes who do not leave messages. Argh!

Unknown caller. I am on the DNC list. These people do not leave messages.

Called me today and asked me to do a political survey. Seemed somewhat legit. After 5 mins, he hung up on me/ disconnected.

Received call from this number. Did not leave voicemail. I called back and got automated voicemail.
