Who called from 3475181429

This is a scam. They called twice, and only on the second call left a voicemail of a robot claiming to be an officer with the IRS, threatening that I had to call back before any action was taken against me. This isn't how the IRS conducts its business.

Scam....acting like the IRS. Wanting you to pay money.  Called back blocked and refused to tell me who or where they are located. SCAM

My husbands phone has been getting hit with these calls... How can you make it stop!!!!
