Congratulations scammers - and I DO hope you're checking these posts - you've managed to get the 321 area code blocked on my phone now too. :o)
FYI to everyone else who continues to be bothered by these idiots. Their calls (illegal of course) are to try to get you to buy into a "free" vacation or something of the sort. Of course though, it's a spoofed number - which means if you try calling back, it's not to them. That's how they "hide". That's part of the reason the FCC and Do Not Call doesn't seem to work. Everyone can and should keep complaining though - and every time you do get a call, just keeping on blocking. If you block the number or area code - that's just one more # or area code that they can no longer use to harass you.
Note to scammers - and I HOPE you're reading this too... Did you know that there's technology in the works (very close now too I understand) to basically cut through the BS & track you down through your IP address? You can run, but you won't be able to hide much longer. You just need to keep bothering enough people so that you become a big enough problem for the police to come get you first. Hey. Have a nice day.
