I was on the phone and received a call from 321-000-6439.
They were sent to the recorder but left no message.
Considering what is written above, it's the usual scam, so I am not calling them back. I'm on the Do-Not-Call list, which they do not respect.
They also called me today. I pressed "9", not to lower my interest rate, but to tell them to stop calling me. When I said I was on the TN AND National Do Not Call Lists, I got the phone slammed down in my ear. Please take a couple of minutes to report telemarketers like this to the FTC. I don't know if it will eventually stop them or not, but it's worth a try. Use this form:
