Saying I am being sued. Very nasty man.

Keep calling me about some kind of legal action. Not a clue what it is about.  Do you know how I can block this on my cell phone. They call at least once a day.

They called saying they could wipe our credit card debt away,

threatened with suit in court

I keep receiving calls from 2024314875 from washington they dont leave messages.You cant call back. My boyfriend answered one and the guy was middle eastern,wouldnt tell him what the call was about,my boyfriend told him to [***] off and the dude got pissed and cussed back. Ive also received calls from a 206 area code it was a machine about my taxes and if i dont call i will be arrested. He states theres a warrent out for my arrest. I called back it was a middle eastern man i couldnt understand him. I hung up. I  called the police there is no warrent, i called the irs they said they dont do that,its a scam.  What legal actions can  we take,Im changing my number,these people scare me.
