called to leave a message and see if my work number was attached to a conference service.

I also got a call from this number today with an automated computer voice to see if my number was a conference call and then it hung up.  Very odd

Received a call last night and the auto-msg said it was trying to verify if my number was a conference call platform. Wierd.

I have also received several calls a day from this unknown number.  No answer.  I tried to call back with my number blocked and it said this number is unavailable.  Not sure how or why they have my number but they need to stop calling!

Calls me every day about 5 times a day, and asks for me by name...

I receive several calls a week from this number.  When I answer, they hang up.  No comments, no message.

7 calls in 24 hours. Never left message. Finally answered and got a 10 second speech on recycling and hung up ignoring anything I said. Very suspicious. Maybe compiling a list of active numbers to then sell? Not sure but don't like it.

They called my brother several times, never leaving voicemails or answering. Finally they said something and asked for me. Which is weird because I never give my brother's number to anyone. Very odd...

A few calls spread over a week. This last one was the first I answered and had someone say something; male voice asking for laura. Told him he had a wrong number and he hung up.

I have a co cell # but no longer live there. This # has called 3 x's/ day for 4 days- various times- i've never answered (always during the day while i'm at work till today). The strange thing is 2 weeks ago I got a call from a similar 720 # saying they were a private investigator & there was a claim out against me. Then gave me a # to call to find out more info. Total scam but I called & they said bogus info -yet had an address from 10 yrs ago in CO (when I signed up for this cell phone). Writing all this here as I believe they are tied- I have gone years without calls from my former state & this is within weeks...don't answer, block # (if they're calling your cell), report #, & move on!

They've called me four times today about every two hours.  I haven't ever picked up.  They don't leave a voicemail or anything.  I suggest we all report them to the FCC: http://www.fcc.gov/complaints.

I just had my 6 times called from this number for a 2 days. I picked up for 25 second then they disconnected.

WOW! I guess I'm not the only one. Got 6 calls from this number this weekend! Anyone know if there is a number we can call to report the abuse or just call local police?  I figure if we all report to the same agency something might get done...

they call me everyday about 6 times. It's ANNOYING!!!!! they wake me up all of the time and I can't put my phone on silent because of my alarm or emergency calls. Please tell them to delete my number from their call list.

This number calls me 5x a day never leaves a message how do I make it stop!?

7 calls in 48 hours. I don't pick up either.

I have gotten 6 calls from 720-606-2387 in the last 48 hours.   I have not answered the phone since I do not know the number, however whomever is calling keeps calling and will not leave a message.   I want these calls to stop.  Six times in 48 hours is excessive.

they have been calling here at least 5 times a day for the last 3 days.

This person has called me 24 time in the last 72 hours, not ok.

I have received 5 calls to my cell phone since Friday, October 19 from this number.  I've missed them all, but after reading the posts here, I've decided to block the number.  Google your carrier and call block and they'll give you walk through instructions on how to do this.

They called once yesterday and three times today so far.  I havent picked up.

i've also been receiving calls from this number.  it sounded like a pocket dial, when they "accidentally" left a message on my voicemail and someone said, "i'm going to recycle you!" super weird.  i agree that we should call the police for harrassment.  if enough people do it, maybe there will he consequences for them to stop.  i have also blocked this number from my phone.

10 calls in 4 hours - I have them "call blocked" through my phone.

Repeated calls, no answer. Call back no answer. "COWARDS"

This number calls my home several times a day & hangs up.  when I call back I just get an answering machine.  I've asked them to take me off there list but they continue calling.

This person calls and instantly hangs up. Has done it several times over the last few days. I have called back and it goes straight to voice mail. Im on colorado no call so we should not be getting solicitations, however this person is not soliciting anything. Why would someone call just to hang up. It feels like they are trying to harrass/ scare people. This person is a creeper.

Yes, I've left several messages but the number continues to call. I'm reporting the number to police the next time they call.

This number has called me several times a day for the past week. I have left several messages telling them to remove me from their call list. The next time they call I'm reporting the number to police.

They keep calling my sister doing the same thing; call, don't say anything but will listen and finally hang up.  A little over an hour ago I aanswered the phone here at her house when they did the same thing  I called and got the same voice message.  I kept calling back then hanging up after the beep ( I don't know if it captured them all, if Si they'be got an hours worth of messages to delete). I hoped this would wither deter them or call the police to report it,which would give me the opportunity to report their activity. However as I typed this post, they called again.  My suggestion to my sister was to call the phone company to see if she had call rejection on her line then activate if she did.  The only other suggestion I would make is to file a phone harrassment report with your local police.

Calling a few times a day.  I'm not going to answer based on what I've read here.
