Do not talk to these people answer these calls or comply with any of their wishes. If this is serious they would have a person calling you directly or they would actually send somebody to your house or you work for real. If you have no knowledge of any debt or money owed then do not worry. Report this to the do not call list
So yesterday I got a call from a different number it started with a443 area code so I blocked it then this morning this number called I don't owe any money so I will be blocking this one how do they get numbers.
