Some sort of State Trooper Association Fund. Not legit. I have called back a few times, and they *do* answer. They hang up after a few minutes of the silence that I dish back at them. Blocked!
So may unwanted calls I now never answer. I pay a phone bill for personal and emergency use not to be annoyed by telemarketers! No message left. Don't know who it was and it's good thing I don't!
