If you have Verizon, you can block up to 5 numbers for free.

People I found the best way to get your phone numbers removed from this company!
I called them back like 20 times and I SCREAMED AT THEM LIKE A FREAK!
After so much SCREAMING THEY HEARD FROM ME...... THEY SELECTIVELY REMOVED YOUR PHONE NUMBER WITHOUT TRANSFERING YOU TO THE VOICEMAIL SERVICE!

Want to stop repeated telescam phone calls?
Try these alternatives:

1.  Do not answer the phone if you see an unknown number on your Caller ID ... let it go to answering machine or voicemail.  Many telescammers hang up after 3 rings.

2.  If you have a smartphone, get one of the inexpensive or free phone blocker apps at your online app store, and learn how to use it.

3.  If your cel is not "smart", read the manual to learn how to set up a "group".  Assign the scammer's phone number to that group.  Also assign a "silent ring" to that group.  You will not hear future calls from that number.

4.  Google NoMoRobo, and visit their site, to see if your phone system is compatible with that system.  (It may or may not be compatible).

5.  Contact your phone service provider.  They may have a facility or method to allow you to block numbers.

6.  If you buy things online, you might want to google "Amazon phone blocker" to see what devices or apps Amazon has to offer for landlines or smartphones. Similar devices are for sale on eBay and other online stores.

The number 1-855-881-2416 keeps calling my cell phone at all times!
Could someone help me how can I stop these freaks from calling me?

This company is a cockroach that doesn't ever die. They keep changing their number and I keep adding them to my reject list. They leave these f****ng annoying robot messages about being a consumer research center that can improve your credit for $100. First, that's impossible. No one can remove late pays unless they are not legitimate.
These people should be arrested. I have posted their number on the DNC list several times to no avail. They are breaking the law.

Black Friday special...it's May 23!!!!!!!   This is a new number for this piece of sh*t company-this is the first time I'm receiving a call from it.....but it's the same lame guy & message from The Credit repair Group, CRG, Consummer... "Get your 720" all of them. I've been put on their do not call list 5+ times and they continue to keep calling. I'm in the process of filing a law suite because of the harassment!  

They use several close phone numbers claiming to repair credit. When you call the number, you get an "out of service" answer.
