These numbers are all connected. They read "Jacksonville" or just the phone number on caller ID and they never leave a message. If I block one number, they just use another one. They all begin with the prefix of "674" (904 area code). If I do answer, the caller is usually aggressive and then when I decline to donate to the fund (it's always something slightly different but affiliated with a police charity of some sort -- so they claim) the caller becomes very rude and nasty. I have asked them not to call and I guess their way around that is to use a variation of the phone number. This kind of harassment should not be legal.
