Called me 3 times (I don't answer if I don't know the number or it's not in my contacts); left a voice message every time with the same robovoice telling me that the IRS was filing suit against me and putting out a warrant for my arrest. Major scam. Deleted them and blocked them, then they called 5 more times with 5 more of the same voice messages from a different number 814-436*3677. Scumbags.
