I received a call from this unknown # at 8 am on 8.15.16. Although this appears to be the first post, I blocked the # because Whitepages.com previously identified it as a "telemarketer" and was flagged as a "suspected scam".
I let it go to voice mail. This number is an automated voice saying it is IRS and that they have a lawsuit claim. At no time did it say a name for who they are calling for just to call the above number for more info. You can tell it is a scam.
