People should continually file complaints with their Attorney Generals office and also file with:
http://www.fcc.gov/complaints
https://www.ftccomplaintassistant.gov
If enough people keep complaining then maybe something will get done.

The calls are being made from outside the US however most of the call centers (where you actually talk to someone after pressing 1) are in the US and the companies making the money from the scam are owned by people in the US. Asking to be removed from their calling list only verifies that they have a working phone number. They continue to call because it is a criminal operation and these criminals do not care about the law.

Many of these calls are coming from Costa Rica and India and they are using spoofed (false) numbers, which in itself is illegal. They do cold calling for or sell the leads to numerous companies in this country and they know that what they are doing is illegal. Tomorrow this same number may be selling Cruises, Timeshares or Security Systems but if you follow the money it usually ends up in the hands of an American LLC. Keep complaining to the FTC and FCC, and start bugging our politicians to pass laws to make it punishable in criminal court instead of handing out fines that they don't pay. Another course of action is to contact phone companies to find out why they won't block spoofed numbers. With today's technology that should be an easy thing to do, unless they are somehow profiting from the use of their systems.

For anyone thinking of using Special Information Tones (or as they're called in the industry SIT tones) to fake a non working phone number, they won't work. Since around 2001-2002, the costs of "digital" business lines have dropped dramatically, along with Voice over IP (Internet) telephone service. Neither of these use the SIT tones as the call information is carried separate from the audio.
This separate call information tells the calling party digitally if the call was answered, busy, voice mail, forwarded, rejected, etc. This renders SIT tones useless. Also the "TeleZapper" products that used to be on the market used this method as well, and were rendered ineffective for the same reasons.
It is also through this separate call information message that the spoofed caller ID information is transmitted.

Robocalls are illegal unless you have given them prior permission in writing (not worded into some small print contract from a 3rd party) and are absolutely illegal to a cell phone.  The Telephone Consumer Protection Act permits individuals who have received certain unlawful telemarketing, such as junk faxes or telemarketing calls, to sue the violator in state courts where they may be awarded up to $1500 for each violation.

Check here first to see if it is one of their phone numbers:

Pacific Telecom Communications Group
Follow JD's recommendations in the blog and stop them at the source.

Many of the disposable numbers come from Pacific Telecom Communications Group and they are currently under investigation and in the midst of various lawsuits. (The principles involved have been part of actions by the FCC under other business names).These businesses have ripped people off for millions of dollars, yet have paid only a couple of thousand dollars in fines. The only way to stop them is to throw them in prison for a few years to make this criminal activity less attractive.

The Oregon Public Utilities Commission has revoked Pacific Telecom's certificate to provide telecom services in Oregon.

The Indiana Attorney General?s Office filed lawsuits against:
Consumer Credit Group and Proactive Planning Solutions of Arizona for violating Indiana?s Do Not Call Law and Auto-Dialer Act known as the robo-call law. Both companies violated the Credit Service Organization Act and Deceptive Consumer Sales Act by not obtaining $25,000 surety bonds with the state and collecting money upfront without performing any services.
Debt Zero of California for collecting money up front, failing to provide services or a refund and operating without a $25,000 surety bond.
Clear One Advantage of Maryland and Credit Arbitrators of Texas for violating the Credit Service Organization Act and the Deceptive Consumer Sales Act by not obtaining the required surety bonds.

Proof that current laws mean nothing to these scum suckers, these same people under different companies have been sued in the past and have only paid a minimal fine. Here are just a few:

Write your Congressmen and Senators. We need CRIMINAL penalties against the companies that are profiting from these calls. Follow the money, slap them in prison, no one left to outsource to overseas boiler rooms, problem solved. Since they are operating across borders it should become a federal felony and should be handled by the FBI under the RICO Act.

Received this call at work about 15 minutes ago (second time today) and pressed 1 to speak to somebody to tell them to remove our number from their call list (I have registered our number with the Do Not Call Registry). I heard fumbling and then people talking and laughing in the background, but nobody would pick up the phone. I have registered a complaint online with the Do Not Call Registry. This really makes me angry. What is the point of a Do Not Call Registry if they can get away with this?

It was a recorded msg.  She identified herself as Heather and said she could help with credit card rates. There was no option to opt out, only hit 1 to speak with someone.

Rachel from Cardholder Services, again!  She sure gets around!

Called nothing left on answering machine

Just another credit card rate reducing scammer.

Caller ID:  800 Service
Number:  855-251-2911

These idiots have called many times and do not leave messages.  They are a total annoyance.  I want them stopped!!!!!!!!

Frequent calls to cell number, no message. Sometimes calling every half-hour. Very annoying.
