I received a call from 360-200-0886 saying they are calling from the IRS and there was a lawsuit against me and a warrant out for my arrest.

I got a call from 903-706-8537 telling me to call them back.  Same as above, I talked to "Officer John Crane" (yea right) and he said I had to pay $6200 or go to jail.  He told me to go to the bank while he held on the phone.  I told him my lunch started in 15 minutes and I did not have a car so I would have to ride my bicycle the five miles to the bank.  After about 20 minutes, I told him I was an FBI agent and I only needed about two minutes more to trace the call.  Fun time.

Got the same messages telling me there were 4 serious a ligation lays against me and I had multiple warrants for my arrest.
