I live in Costa Rica, and they have called my cellphone twice this week, I couldnt answer the phone when they called and offcourse I wasnt going to call from my cell, so when I got home I called using skype and it rings once and then the call drops..

Who do you think you are to tell me my business?

I received this call too, but i dont know who are ? any ideas ?

I got this call too last week and now my telephone bill (from ICE the provider in Costa Rica) came with a bill of almost $150 on international phone calls that I never made, this is a scam.
I did an investigation and even if you dont answer the call and the answering system gets it, they´ll be able to use you for a mann in the middle attack, I guess the only way is to press "ignore" the call

I´ll get to the bottom of this and let you know

unknown call
