Same thing as above. I called and nothing.

Several calls on cell phone. I do not answer or call back. No voicemail message left.

No one answer and they keep calling. Pretty much everyday.I don't want them to call me. They even not answer when call back.

Keep receiving calls from this number with several extensions so far.  Keep blocking them and they use a new extension number. No voice when I did answer, and no one picks up when I called.
