DO NOT CALL BACK! Scammers are using this method so you do call the number back HOWEVER, the line will be a dead tone or an operator will ask you told hold. While your holding you cell/land line will be charged a per minute fee on top of an international rate. If it happens to you chances are your cell phone carrier won't do anything about it. You need to file a complaint with the "Federal Trade Commission and Federal Communications Commission"... Hope this helps... I had an email from my NatSec this morning about this and just received a call 20min ago that rang once and googled it...
I have filed complaints with the federal trade commission they told me there is nothing they can do that they are robo calls and not to answer the phone sometimes I might get 25 or 30 in one day seems like these would fall under homeland security because they clearly not American calls
