called repeatedly 9:30 9:32 9:33 so I finally picked up. nothing but what it sounds like when a person is walking with a cell phone in their pocket that has dialed on its own. Men talking to some other ppl about making money and border patrol??? Hard to hear entire conversation because I was more interested in Shark Tank. :) But obviously they didnt know they were calling THIS TIME.

Calling my number multiple times - I igore -but finally answered it - and they just hang up..
Annoying .. JERKS

Calling sometimes 5 times a day, We have asked for managers and they hang up. we have asked them to stop calling and they still do.

They even call me in The Netherlands! WTF!

Same situation.  They call about three or more times a day

This number call my work place asking for a a former boss that has left the company. Every time they call I ask that they take the number off their call list and each time I get hung up on. I'm making sure we are on the do not call list and think it's time to file a complaint.

Lady said she was with Hart Energy,  When I look up the phone number I got this site...

Called today, asked to speak to my predecessor's name.  Was underground so the secretary sent it to voice mail.  Left a three minute message of just dead air and background noise.

Salesman.  Woman with thick accent called at 6:00pm (I was working late) and asked for our company owner by name (he does not work in this area).  I said he was unavailable and asked to take a message, when she said she needed his assistant.  I told her they were both located at another office and again asked if I could take a message, at which point she got pushy and said she insists I give her his assistants phone number.  I told her she will not get that number from me and she hung up.

YES OBAMA!!!

They called, and had the name "Black Diamond" on the caller ID.  They asked for one of our employees by name and I said he wasn't available.  They asked for his admin, and I said that was me.  They then asked to confirm a free subscription renewal for him, and I told them that they would have to contact him at home for that.  When they asked for his home information, I said "What do you have on file?".  They did not have his accurate information, so I told them that I could not give them any information as they did not have anything that indicated they were an honest company that had actually spoken with him in the past.  I have asked them to stop calling our number, but I still get a call about once, twice, and sometimes thrice a week.

Some heavy accented Indian lady asking for an employee.  She completely butchered the name.  I hung on her

Thank goodness for caller ID. It came up on the phone as 'Black Diamond' and I didn't pick it up, hit the button to send it to voice mail on suspicions of a telemarketer. They instantly called back and I sent them to auto voice mail again. No message left.

Caller ID reads Magazine Subscr.  They called twice today and hung up the first time as soon as I answered.  Second time a woman asked to speak to CEO by name.  I said "no".  That caused her to hesitate, and then she asked again.  When I said "put us on your do not call list" she hung up.

Real pests.  They are only supposed to verify subscription info once every year, but Penton does it every 3 months!  I am a busy professional and I do no have the time to talk with them.

thye call and hang up

This number has called multiple times. They do not leave a voice mail. Have answered once, but no one speaks on the other end.

This number keeps calling leaves no message. When I call back there is just music.

Similar to the others, I had a Missed Call on my work phone from 9044504828 on 10/17/2012 at 12:11pm. The ID was same as other calls above: BLACK DIAMOND P

904-450-4828 Displays as "Black Diamond".  They have called our U.S. Headquarters' switchboard in Massachusetts 7 times in the past few days.  They are searching for names that are not on our list of employees.  I asked if they were Telemarketers but they would not answer.

Called 3 times in last week, never leaves message except for last time, where she left a 2 second, barely understandable messages that sounded like she was addressing my 1st name but then it just cut off. I suspect telemarketers because I have no debt, so collections are not possible... FREAKS!

Person asked for Engineering Manager- when we asked for more details about the call, they hung up. This was after 3 previous calls and they rudely asked to be transferred.

Same deal the past week calling my business line, no msg, number on screen not in service?

A woman called and asked for the owner of the company, when I said the owner was with a Client, she then asked for the assistant. I informed her that was me and she said all she needs is the owners personal information so she could send out a publication.... You DO NOT need to know the college the owner went to to send a magazine out!!!

They keep calling, but never leave a MSG.

Woman with difficult accent asked for our production manager and mangled his name horribly.  When I connected her he let it go to voice mail.  She immediately called back and asked to speak to his assistant.  When I told her that he did not have one, she asked to speak to "anyone in charge of design or facilities".  I asked if she is a telemarketer.  She would not answer the question, so I told her that she should leave him a message.  She hung up.

Received call from this number, noiose in background then hung up.  Called back and got message that the number is not in service.

Called my office...did not answer...no message.

They have called my work number 3 times.  BLACK DIAMOND P on caller ID.  Have not picked up.  No message left.

caller was silent then hung up. 904-450-4828. Caller Id said "Black Diamond P "
