Received call from this number. Answered and never got a response. They called 2 times within an hour.

Claimed I supported them before etc...

I called back a few times, there is never an answer--only an answering machine. the message indicates to leave your name and number -----(they do not identify who they are though)!!!

if you get a call from this number, don't say anything beyond 'hello'. it could be recording voices for voice-activated bank services or something

Got a call claiming they're working for crimestoppers.  I was suspicious and asked if I could call them back and they gave me the number 1-+1 800-519-3344.  Some guy answered with hello.  When I asked him who I had called he said, "who are you looking for?".  Sounds more like Crimestarters than Crimestoppers to me...
