Called me with the same explanations (warranty). The got my full name and the exact vehicle model, asking for my current mileage reading. I told them the value and they asked to stay on the line while they were checking something and then eventually hanged up. Never called me back
Robocall to business line from a "Economic Relief Center", supposedly out of California, even though it's a NJ number. No business registered in that name in the California SOS. Do not give them any real information, as they are likely a scam. Agent did seem to be from an US-based call center, so complaints to the FTC may result in something. Also, you might want to complain to the California Secretary of State at http://www.sos.ca.gov/business-programs/vcfcf ... on/email-vcfcf/
If you want to play games, just note that your 'debt' needs to be more than $15,000 for them to talk to you. I provided a too low number, so blew my chance on this call. However, they will likely call back.
