I had the same call in the same issue. They said that I owed $3000 after they audited my taxes and that there was a court hearing in two hours. If I didn't make the court hearing I would then have to pay legal fees of $6000. They said they sent a certified letter but it wasbut it was returned to them. So that I needed to do something immediately. It was the same number and same name. I got the message saying it was urgent that I call back and so I did.
