I am being called at my job,threatened with the marshall coming to arrest me at work. Saying I owe them 1500.00 and they have taken out a warrent for my arrest, but they won't tell me what law firm they are from. they are leaving threatening messages at my work.calling my phone constantly, telling me to buy a pay power visa card and put 200 on it, I unfornately did that, now they say they can't accept the 200, because I owe them 1500, but whenItried to get infor on power pay card it was invalid, they couldn't validate it.
