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.
I don't answer #'s I don't recognize so I got this info as a voicemail. It began automated stating that the call was for my boyfriend. We have separate cells so no reason to call mine. Then a woman says she received a fax regarding a complaint against him and that she had been "retained to serve you with documents to appear either at your residence or your place of employment. If you have any questions or concerns about the complaint or wish to rectify the matter you will need to call (automated voice gave 802-881-0607). When calling please reference file # v(or Z)ol2734432. You have officially been notified." No name was given of either the company or person calling. I immediately looked up the number online and found this site. We have no idea what this may be referencing or how they got my number. Thanks so much for the info provided by others. I plan to call my carrier (At&T) to report this as well.
