Received a call from this number just b/f lunchtime. Three second voicemail with no sound = Blocked this caller.
Do Not Call Listing works - however they can't prevent robocalls or calls from unethical telemarketers.
Called my cell. The ID reads "FL, USA". I didn't answer. They left a recorded message that was only partially there. All I got was "to speak to a representative. Press 9 to opt out." I didn't press 9. I don't believe "opting out" does any good at all. I did, however, block the number.
