You receive a call from someone claiming to be from the court saying that you missed your Jury Duty summons and there is now a warrant out for your arrest. They tell you there is a fine and if paid the warrant can be voided.
Green Dot Cards
They instruct you to go to a grocery store and purchase "green dot" cards and call them back with the numbers. This is a scam. If you do happen to miss Jury Duty, the court can impose a fine and/or jail time but you will never be asked to purchase "green dot" cards to clear the fine. You will need to go to the courthouse to do that.
