Got a call from this number while I was at work; the second I answer, the woman on the other end starts yelling that I hung up on her, & that she wanted to cancel some service. I tried to politely let her know that I hadn't hung up on her, & to obtain the phone number on her account so I could assist her. She started rattling off numbers with no area code, very quickly & almost under her breath, then told me I had a snotty attitude. I told her I was trying to assist her & requested her number again. She then gave me a DIFFERENT set of numbers & again said I was snotty. This happened about four times before the phone line went silent. I let the caller know that I couldn't hear her but that I wouldn't hang up, & would wait to hear her. She then hung up.

I got two calls from this number today while at work. The caller ID said Boulder, CO. It sounded like a little Mexican boy breathing in the phone both times and they would not respond to me besides heavy breathing and gibberish. It was really f*ckin creepy and part of me was like uh is there a ghost calling me?! That's how creepy it was.

a bunch of little girls prank called me from this number at our private investigation.  I don't understand why they just giggled.  Its a voip number and u can't call  from a blocked #.

This guy has called our dealership 3 times today saying he is interested in buying a car from us and having it shipped to Nigeria.  Claims he has an agent locally who will handle all paper work but wont give name or number.  Has awful accent and says he's in Nigeria on a christian missionary trip.  SCAM!

I'm a chiropractor and this number calls me with no one on the other end.  when i call back it's busy.

Some retard called my pizza place and asked my phone girl if we sell Chinese food. She said no, and the caller said, "okay, I'd like to order 4 pints of rice." Then we hung up on her. I tried calling it back several times (*67) out of curiosity, but it's always busy. It comes back to Denver on White Pages' website, probably a pay phone.

This guy called my work at 10:30 lastnight saying he ordered products from us and they were contaminated. My job doesn't even sell products. So i went to switchboard and google to research for myself and found this page. I dont quite understand the AT&T thing everyone is saying....when you *67 and block your number it comes up private or blocked id or incoming call depending on what service provider you use....

For phone number 303-444-7428, he requested a make/model of my copier machine.  From what I have heard in the past, people will call companies asking for the information on their machines.  Then, they send toner to the companies and then invoice the company for an unusually large sum of money ($100-$200 for a toner that would cost $15-$20).  Some companies may pay the bill not aware that it is a scam.

This number is from a phone carrier called Telmetrics. This number is a GENERIC ANI (number) shown on caller ID for any calls passing through their network with less than 10 digits. It can be hundreds of different people that are calling everyone even though the number is the same on caller ID. again only a generic number used as a placeholder for calls in which Telmetrics cannot obtain true caller ID.

I received this call at work and I knew immediately I was a prank. There was a guy who was using an old man voice. He was asking for an insurance quote. I asked him a couple questions and didn't feel like playing his game so I hung up. Then a lady calls back and says how dare you hand up on my grandfather. Is it because we are black. I knew it was a prank from the brgining. She used some vulgar lanuage and kept ranting on an on and hung up. Called 303-444-7428 back but its just a busy signal.

we got the same creepy phone call at our work a few times now and i knew it had to be the same person because of the creepy soft voice. we totaly thought we were being punked too.  i tried to call the number back but all i get is a busy signal

Call was to get info on Office Copier so they can send out new supplies (because they support our copier) SCAM SCAM SCAM

This is an unknown ans unwelcome caller who calls at inapropriate hours.

guy with thick accent just called my office number - said he worked for cosmopolitan magazine and wanted to do a quick survey. i hung up.

This guy called out office and sternly asked to speak to a manager or owner about an on going investigation! When I started to a reply he hung up the phone.

little kids calling and asking stupid questions when you ask to speak with an adult they hang up.  you can't call the number back for some reason.

Received a call today, very rude and vulgar.  I informed that I do not have to stand for that type of language, he asked to speak to a manager and then hung up on me.

Very abbrasive and seemed to have a group of guys in the background (much like it was a prank phone call) laughing and talking to him.

Someone needs to find this a**

I know it isn't someone our company hired. I just got a call from them, and being that we own our company, I know it's not a secret shipper

this number called me today (july 19 5:30)and order $88.00 worth of food this number is what showed on the caller id but the number the guy gave me was 873-9333. i always cal back and verify the order if they give us a different number that what they call from, and when i called the number it was another pizzeria... and its just so happens that their add is on the same page as mine on the phone book... good thing i verified or i'd be out all that food... the guy used the name Manny James  and sound drunk like others have stated

THIS PERSON HAS BEEN CALLING AND ASKING FOR PIZZA DELIVERIES, TOWING SERVICES, TAXI SERVICES, YOU NAME IT..  WE HAVE BEEN BURNED BY THIS PERSON BEFORE.   I HAPPENED TO REDIAL (*69)  AND CAME UP W/ AN OUT OF STATE NUMBER  303/444-7428  WHEN THE IMPERSONATOR  GAVE A POOR INNOCENT PERSON'S NAME AND PHONE NUMBER FOR SERVICES.    HOPEFULLY THIS PERSON WHO IS DOING THIS GETS WHATS COMING TO HIM SOON.   A** H***

A woman called from CID 303-444-7428 saying she needed to speak to the owner of my company.  I asked what it was in reference to and she said "an investigation of accounts due".  I said  ?due you or due us?? In the same tone she was speaking.  She, rather than answering my query, said I need know who that would be in an even fouler tone so I said I think you need to leave a message and she promptly slammed the phone down.

We got a phone call from this number asking about pricing for pool service. My husband cleans pools and got the following name/address for this person

Name Vell Kaur

Address  3858 Via Linda drive, Glendale AZ

He was going to meet this person at this location tomorrow to bid on pool service.

After reading all this,,, I think NOT!

We got a call from this number today.  It was a woman asking about "pod" storage.  I directed her to pods.com, she thanked me and hung up.  I was curious about the number because our head office is in Denver and we do get shopped.  I must say this thread has been really entertaining.

Received 2 phone calls from this number today 303-444-7428(caller id states its a Colorado Call). The first time they called our office the caller on the other line hung up, then called back several hours later. Its is a guy who is a complete weirdo, he was saying things like I just want to talk to you, will you please just talk to me. After about 2 minutes of him being a weirdo I just hung up. What is this persons deal? Don't they have anything else to do besides harrass people who are actually working!

I use Telmetrics which is a tracking/reporting service. When someone calls from a blocked number it automatically shows up as this number. It could be a telemarketer who normally block their number or it could be a real customer who just happens to have his phone number blocked on his cell. I saved the number in my cell as "blocked call to Telmetrics". It's not the same person calling you over and over again. Now when I get a call it pops up in my caller I.D. as "Blocked number to Telmetrics" and I decide whether I want to answer it or not.
