Debt collectors or their minions are disallowed from making threats and doing certain other things.

If you KNOW you owe no money, or believe the call was from a fake debt collector, please take the time to read this:

If you DO owe somebody some money, you should read this:
This is a long summary, but you need to read it carefully if you think you are being threatened by a debt collector.

The Fair Debt Collection Practices Act (FDCPA) includes statements such as this:

* Every collector must send you a written ?validation notice? telling you how much money you owe within five days after they first contact you. This notice also must include the name of the creditor to whom you owe the money, and how to proceed if you don?t think you owe the money.   ["Written" means snailmailed ... not emailed or texted]

* Debt collectors may NOT
- repeatedly use the phone to annoy someone.
- falsely claim that they are attorneys or government representatives
- falsely claim that you have committed a crime
- falsely represent that they operate or work for a credit reporting company
- say you will be arrested if you don?t pay your debt
- say they?ll seize, garnish, attach, or sell your property or wages unless they are permitted by law to take the action and intend to do so
- communicate with consumers at their place of employment after being told this is unacceptable or prohibited by the employer.
- say that legal action will be taken against you, if doing so would be illegal or if they don?t intend to take the action
- use a false company name
- take or threaten to take your property unless it can be done legally;

The debt collector may not garnish your wages unless there is a court order to do so.
+ Many Federal benefits (including Social Security Benefits) are exempt from garnishment

You have the right to sue a collector in a state or federal court within one year from the date the law was violated. If you win, the judge can require the collector to pay you for any damages you can prove you suffered because of the illegal collection practices, like lost wages and medical bills. The judge can require the debt collector to pay you up to $1,000,

Report any problems you have with a debt collector to your state Attorney General?s office, the Federal Trade Commission, and the Consumer Financial Protection Bureau.

Dealt with this number months ago. Calling again. We are not people they are looking for. This company "Union Group" is supposedly out of Denver, Co. They employ "locators" (in which they will not give you any kind of information on in order to "protect" them). The locators numbers come up blocked or unknown. They have threatened and harassed my children, my elderly parents non-stop.  15-20 phone calls a day on each phone plus messages. My kids are all school age.

We have voice mails were keeping. Total harassment. What else did the lawyer suggest?

Did the same thing except said they were "the firm". Very annoying

This idiot from this number calls from this number stating they have a claim against me. Have no clue who these people are they are harassing my family and friends no idea how they got their phone numbers.  This person trys to sound professional stating he is investigating my claim snd they need to verify my address.  Well if I owe you something you should have my address it hasnt changed in 10 yrs. Contacted an attorney was told to record the calls so that's my next step and fing a formal complaint.

got a threatening call supposedly for someone else. said needed to contact 'the company' gave this number & a number code.
Think it is some kind of extortion or scam. They called from a blocked number.
