rude telemarketer.  She asked for a coworker I advised He was not here and if I could help, she said no and hung up.

Very rude.  The woman calling asked for a co-worker.  I said he was out of the office and asked if I could help her.  She said no and hung up.  This is the 3rd rude call I have received at our office and they refuse to leave a message.  I attempted to call the phone number back numerous times to complain about the rude phone calls but it is always busy.  What is CMC?

Asked for some one who isn't reached at this number said his name was Derek Pendalson asked what I could help him with he said nothing that he would call back later then hung up.

Constant solicitor

Caller ID is CMC, there is no one at the other end.
