I probably got at least 10 of those same phone calls threatening to have me arrested if I didn't pay. Since I am in law school and couldn't risk having a record, I paid the first time it happened to me. Then I talked to a lawyer and came to this site and realized that what they are doing is just harassment and scare tactics to try to get you to pay. So, I sued them back!!
Like I said, I have received probably 10 of those phone calls and nothing ever happened to me. It's also funny because as time went on, I used to mess with them and I would ask them what the exact charge would be and asked them to cite the state law they would be arresting me under; they could not. I asked them what jurisdiction they would be charging me in and they didn't even know what city I lived in. It was rather amusing.
I still get those phone calls about every 6 months or so but I just tell them if they call me again, I will be tape recording the phone call and the tape will be turned over my lawyer to press charges for harassment against them!! They never call back.
