just block/decline the # if you do not recognize it, every time you respond you are verifying yourself as a target for these types of unsolicted calls...even my junky low-tech Tracfone has this option! I do not answer the call & then immediately look up the unfamiliar # on this site, easy! safe!
Just called a cell that I only use when I'm walking the dog. They must just be robo dialing because I never use this number for anything. Didn't answer it and no message left. I see they called on Tuesday as well now that I check the call history. I've been on 10 cruises so maybe I'll take them up on the free offer. lol
