man had my name and insisted he could lower my real estate taxes, he said it would cost me very little and save me a lot of money. I just hung up.
I did a reverse and found it was an unlisted phone from Baldwin, Florida.

Got a call from this number today from a guy who called me sir (I am not a man!) and asked if we have dental insurance. Needless to say I told him to stop calling us.

I did not wait for them to say anything before hanging up.  When there is enough of a delay after you saying "Hello!", you can rest assured that the call is from a mass-call center.

I called back, and an automated announcement identified themselves as Property Tax Relief.

I thought it was illegal for anyone to call if your number is on the Do Not Call list (which mine definitely is!).

2nd time called dead line did a *69 got this number. Looked it up and found this forum.
