I get bothered by the same foreign accent sometimes 3 times a day threatening me with jail time and my soc sec number being suspended (which doesn't even make sense) unless I pay two thousand to ten thousand dollars ....I've gone so far as to yell and scream and threaten this person if they don't stop...and every number they call me from says it's not a working number or it belongs to a person who has no idea what I'm talking about .....how can I make this stop ....please help me ....
