Callers are located in India and Pakistan.  There's nothing the US can do and the local governments do little.  Invest in a call blocker and DO NOT pick up on numbers you do not recognize.

This number call me sounded foriegn couldnt understand him as his phone keep breaking up, i asked him why i couldnt call the number back as he already called once and i attempted to call back the number didnt work, telling me im approved for a Govt Grant for a home which im already a home owner and never signed up i ask him give me a number i can call back and speak to a manager he hung up on me

Wouldnt stop calling... He knew my name... He wouldnt say who he was... I want him reported

I usually just hang up, yesterday I asked that they remove me from their call list and was asked why I said because I requested that you do so the guy said no and I will call you everyday all day if I want to, I said and I will sue you he said oh so you're going to shoot me and I flip the script and said oh so you're threatening me and my family, we went back and forth and I hung up.  He called right back and I said f... you, and he responded oh so you want me to f...you. I told him to f... all of his female relatives of course being myself.  He called several more times after that but I didn't answer. At any rate it's a shame that their claiming to be the federal government and government isn't doing anything to make it stop.

When they call i cant undertand them and their broken english. When i tell them to put me on their do not call list they hang up on me. Very frusterating.
