Called me 5 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 3 more times with 3 more of the same voice messages from a different number 814-436-3689. Scumbags.
