This is a scam.  These people curse at you, and tell you that you are going to jail if you do not send them money.  When asked who they are, they told me a law firm.  When I asked which law firm, they could not come up with one for three minutes, then said "global law firm".  These are muslim people trying to steal money. The arab or muslim man that called said he was calling from CFS financial.  Then it was global, they are lying and trying to steal money from you.  The first time the man said his name was Danny Black.  After calling back a couple times, I got his voice mail, which said "Joe" black.  Then, I decided to keep calling.  20-40 times a day I call and do not say anything.  Now his name is Andy Schwarztmere.  Every few days he changes his name, and then begins to speak a muslim, or middle east language at me.    He has told my wife the he will f*** her, and my daughters.  So, my suggestion, just keep calling him.  He finally got annoyed after about a week and asked me to please stop calling so he could do his work.  Each day I block my number, and continue calling, with the phone on mute, and speaker, and wait for him to say more.  They have finally stopped calling.  They are a scam, they will curse at you, and they do not care if you tell them not to call.  They even call you at work.  Join me in the fight, and continue calling them when you are bored, and listen to their responses.  It is actually quite hilarious.
