I just got the same call and they said I have a complaint against me. :-) Said to call back with a coded number they gave me. So I called back and used *67 to block my number and it was a recording but said it would connect at the next available representative but it hung up on me. So by that I am sure it is all a scam! Be careful.
SCAM SCAM SCAM!!!! Idiots robo-called a lawfirm (me) for a former employee giving her name and saying a lawsuit was going to be filed against her. 1) Creditors CANNOT threaten an action they have no intention of taking; 2) Creditors cannot give any information to a third party; 3) they cannot use misrepresentation or deceit; 4) they must properly identify themselves and 5) they must properly identify the original creditor. I repeatedly called them back to get a live person and told him cut the [***] (I used nicer language), they hung up. DO NOT give these people ANY information. No one will ever call you to warn you you're going to be sued. That's harassment. You'll just get served with paperwork. I don't care what information they already have on you or "verify". If you get a live person who says they're going to sue you, or have the marshals come or sheriff or whatever, tell them to bring it on.
I am in Phoenix, AZ and have been getting robo-calls from (802) 881-0607 for months. I know that it I a scam and have recently blocked the number from my cell phone.
