I just received a voice message from this number telling me I am being sued by the IRS how do we stop this from happening I think some how I was hacked I have received 6 calls within the last couple of hours from all different numbers this is the only one that left a message

It's a widespread scam. Google IRS SCAM and put your mind at ease. Ignore any future calls. For that matter, don't answer calls from unknown numbers.
