This number keep calling me and when I answer they hung up!!

annoying calls , they called me all day. left no message

I have received 18 calls in the past hour.  The last one I picked up and it was the end of a recording saying only "Goodbye".
I'm on DNC list, but does no good.  It's not enforced.  I read about suing them, and you can win a case but not be paid, so that doesn't help.  It's really creepy and annoying.
I think I'm going to get another GV phone number to use for everyone I don't personally know and only give my real #  out to close friends/family.

43 and counting..

Well you can add another # to the list 315-325-4170... I never answer and they never leave a message....4 calls from them  just today.
