I am really hating this calls and I want them to stop calling.

calls about once a week never leaving a message, just hangs up - annoying interruption to look who's calling only to find it's some spammer again. Finally blocked the number.

Let us know when you get em!

Call came during dinner, and my 5-year-old daughter answered it, thinking she was doing a good deed... the guy on the other end started cussing at her, she cried and ran to her room, I heard the rest of the cussing, but the guy hung up before I could shoot back. My husband has the number and took it to a ham operator who knows how to trace calls. Once we find this scumsucker, we'll file legal papers... Kimmy's still crying, I'm typing as I hold her.... I'm one pissed off mama now!

I never answer numbers I don't know and this one didn't leave a message.  Reading what I've read so far I'm glad I don't answer unknown numbers!

I just received a call this morning 6/19/14 on my business phone!!  This phone is registered and paid for by my company.  They don't leave a message but have called every day this week.  When I called back it says they are ERC????  No clue who this is.

called cussed, and threatened to take legal action if they called my number again. then I went to the Feds and put my numbers in the do not call list. then went back and put the number they use in the do not call list, I will screw with them any way I can from now on! Don't know if will do any good, but It seemed like a fun thing to do at the time.

My complaint is the same as Maggie's.  They called on 6-17-2014, approximately 5:00 p.m.  My phone rang once and stopped ringing.  I did look at the number, however and have decided that if they, in fact, DO need to speak with me, they will leave a message.  Best practice I have found is to not answers calls from numbers you do not recognize.

Just got a call from this number.
Called, rang once and then that's it.

Rings once, no voicemail. Probably debt collection for the last a** that had my number. Lots of people out to get him, including me at this point.

Received a call today (3:02pm). Claims to be a debt collector looking for Jason Knotts. I told them he doesn't own this phone. They asked if I know of a Jason Knotts. I told them I do not. She proceeded to tell me they are attempting to collect a debt and the phone call was being recorded. I told her to record this and hung up. They do this all the time. It's SO OBNOXIOUS!!!!!

Calls, it rung once then hangs up.

Robocall... spammer... loser and coward.

Same here calls and hangs up.

got a call rang only once. pretty sure its a debt collector robot making sure the line works.

This number called me and when I answered the sounds of hell played for 30 minutes and then a voice uttered a racial slur and hung up

This number calls and it rings only once. I've  had 5 or 6 calls. I'm not calling back.

>>  I wish there was a way to block these numbers!  <<

There is!
Visit your app store, if you have a smartphone.
Otherwise, assign those numbers to a group called "spammers" (or something similar), then assign a silent ringtone to that group.  If you do not answer, do not listen to voicemail, or do not view any text message, you will not get billed.

They call on my new pay-as-you-go phone, and they hang up the moment they call! Ugh!! Are they trying to use up all my minutes?! I wish there was a way to block these numbers!

Same thing just happened to me a minute ago. They call and hang up while calling!

same here! a year later and just calls then hangs up. weird

Call me to sick of this!!! Its calls from all different numbers

ERC collection company

Just called and hung up no message

one ring call warning don't call back it will cost you $$$ its a international call and you will charge on you're phone bill its a "scam"

Phishing call I think.  Said they had a delivery on first call and wanted finance info.  Watch these people.

I pay by the minute, their calls are costing me money. So NOW they owe me!

Calls and hang up

Calls and hangs up.

It rings once, maybe twice, then stops. I just added it to my blocked list.
