720-240-9740

Never seen number

This number and 2 others exactly like it (except a couple of digits of on the last 4) called me 3 * in a row and then hung up. It only rang once each time but EXTREMELY annoying!!!!

This number called,when I answered I got no response then I called the number back and it didn't even ring!!!!!!!

Got a call from 720-240-9740 & 720-240-9785 - (DIDN'T ANSWER THEM) but thought I would share with all!!!!

720-240-9740
720-240-9308
720*240-9785
all these numbers call and when i do not answer leave a LONG blank space on my voice mail, a CB results in a busy signal.

This number called, I didn't answer, it rang once time. When I called back, the connection was interrupted, no answer.

I keep getting repeated annoying calls from 720-240-9740 and 720-240-9308. When I answer no one is there. Who is it???

Ive received calls from 720-240-9740, 9785 and 9308 repeatedly, and back to back, on bothmy personal and business cell phone. There is never a message and the calls come within a half hour, a few times per day- then nothing for a day or two. The 9740extension calls several times during this time frame. Sometimes both phones are ringing simultaneously or back to back.  Who r these people and what use is the do not call registry?! Please stop!

My phone didn't even ring, or if it did it was only once.  Only noticed it in my missed call log.  No message.  I did just spend a week vacationing in the Denver/Boulder area, no idea if that's relevant though.

Same here, got a call from this number, and its just a blank message of silence on my voicemail.  I have downloaded a call blocker app on my android and when this number called me, a screen for the app popped up and said that it "detected a malicious phone number" that called my phone, and would I like to block it. Of course I blocked it. I have been repeatedly getting these scammer calls from "you owe money for a payday loan from OVER 11 years ago (which I don't), then calls saying I have been selected to receive a "holiday pay day loan" (which I never applied for, or want, or need one), and then this week it is different numbers with just blank messages for 5 minutes, and today at 8:31 am.  

I had the same experience as dude in that my phone didn't ring or it rang and was hung up. I have a missing call that I didn't even hear come in because I was listening to music player on my phone so that's improbable. Although, I've never spent a week in the Denver area.

I received a call this morning from this number, it only rang once then left voice mail from Med One Solutions. The are a medical debt collector.

It has been awhile since this number called me but it has happened before when I answer it is dead and I don't hear a click from them hanging up. I would like to annoy them back.

I was on another call when this number came up on called ID. When I clicked over, there was just dial tone. I tried calling the number back and the call wouldn't go through. I tried from my landline and got the same. Basically, my experience was the same as others who posted here. I just hope that it's not a repeat annoyance as others have reported. There's an option on my phone to block specific numbers. After reading these posts, I believe I will take advantage of that option. Am grateful to all who shared their experience(s). Thank you.

The number is from Bonneville Collections...at least for me, they're attempting to collect on a power bill from last year.

Collection Agency

i recieved a call and no one was there if it is a debt collector you would think they would at least harass you and tell you why they are calling instead of complete silence!!! you being silent on the other end is not getting any owed debts paid just aggravating several people!

Bottom feeders, sorry ass people that can't get a real job

called me several times and no one was on the line.
