Just filed a police report for them a***oles! Called my whole family annoying a** people will never call again

How can I block this number?

This is a version of the you-have-committed-a-crime extortion scam and you are being...
1. charged with fraud or passing bad checks or embezzlement or
2. served with a court summons or arrest warrant or bench warrant or whatever or
3. located in preparation to being served or for a lawsuit or to be arrested or
4. sued for cable TV usage that you've been stealing for years or
5. whatever stupid crap reasons they will think up next.

And you have to...
1. call back with your case number or
2. confirm your address or SSN or whatever so you can be served or your papers can be processed or
3. pay $895 now to avoid paying $5,000 in court or
4. whatever stupid crap reasons they will think up next.

Beware extortion scams come in many flavors and they constantly evolve to stay one step ahead of the law.

The BBB has issued several alerts on this scam, just google "bbb.org alert phony debt collector"
Never do what they tell you to do but report them to the Internet Crime Complaint Center http://www.ic3.gov/complaint/default.aspx , the Federal Communications Commission http://esupport.fcc.gov/complaints.htm , the Federal Trade Commission https://www.ftccomplaintassistant.gov/ and your state AG, as appropriate.

Your phone company probably offers something called Selective Call Rejection (*60 Activation, *80 Deactivation) that allows you to block a limited number of calling numbers but this may not be very useful because your caller is probably spoofing his number and they can change their calling number anytime. Selective Call Acceptance (*64 Activation, *84 Deactivation) may work better because it blocks all incoming numbers except for the ones you whitelist but I think the whitelist is kind of short so this won't work well if you have a lot of friends.

How do you block the number

Yep - it's an annoying collector that will call 3-4 times in a row.  Block the number ASAP

I just got off the phone with them - Indian accent with names like Andy Hunt and Daniel Cooper- who are these people.  They are threatening to call my employer.  I just hung up.

Its the INDIAN accent fraud/scam people trying to act like a law firm. Dont fall for this scam, all they did was change their number, they have been using the magic jack to make phone calls. They have your information and want to scare you in beliving that if you pay a amount of money the charges will be dropped. There are no charges againt anyone. They dont record their phone calls all they record is when you give them authorization in withdrawing money. They will tell you that the call is being recorded but its not, they will get mad, insult, and harrass you if you keep this going. There is no stooping them. Just hang up pr harras them back, thats what i am doing.
