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.
Voicemail was left. Person called and a taped different name than my own was dropped in. Stated fraudulent activity was linked with me , if I did not call back before summons were received I would forfeit my legal rights. They provided a case number.
