Fake IRS scam. Said the IRS was filing a lawsuit against me. And tries to get personal information  like name, DOB, and SSN. Didn't give any information and kept asking who they were trying to contact. He said he had all my information and needed to verify it. But he would say who he was trying to call. When I kept refusing to give my name he said the police would be here to arrest me in 45 mins. Still waiting. Hahaha
