Called asking for Frank...I've had this number since I was a teenager so definitely no Frank at the number.

New spamming number, tried to lure same-area-code tendency.

Called asking for Kevin a couple weeks ago. I told them they have the wrong number and they hung up. Today called again asking for Kevin. When I told them they have the wrong number they began asking for donations to help families of police officers killed in the line of duty. Real heart tugging line. But I told him that since I cannot verify his credentials over the phone, I am not giving them money. Caller hung up.

Called but left no message

This sounds like a person calling but it's a recoding that's why they hang up.  If you say don't call it is programmed to the don't call list otherwise it will continue calling
