This is the same scam I posted about earlier , but this one is coming from a California number rather than Minnesota.
Its a fake IRS scam.

Got a call twice today from this number and the first time they left a message saying that they are the IRS and they are sueing us. Well first of all the IRS will not call you, none the less call from a cell phone, second they would not leave a message with stating a pacific person. One big scam!! I blocked the number.

Got same phone call three times this morning. I can't believe this is legal.

They have called me 3 times today. This is extremely annoying!

Scam. Acting like IRS. Do not call back.
