I just did not sure who they are.

Just called my home.  Internet search says NACA, a non-profit.  Only listened to part of the message offering a free event where you can get an affordable mortgage.  Will be adding to the "junk" list of callers on my iPhone contact list.

naca.com - not a non-profit, a mortgage scammer.

clear violation of do not call law. scam, scam scam.

Just added them to my blocked calls list.

I love that feature on the phone!!
