I just got the same call and for the same money, and I live in the mountains of Georgia, and barely ever drive to the cities.  this freaked me out...they wanted me to send the money through a green dot money gram at Walmart in the next hour. they would not tell me when and where this ticket of speeding happened. I called to my sheriff  and they checked the national data base to see if I actually had a warrant like these idiots said I did, and I did not... My police dept. said to NOT send them any money or give them any information...I hope these creatures are caught and punished!!!!!!
