Its a IRS Phone scammer...Its just a scam to steal your money...They will say they are officer BLA BLA BLA and they need $500 to 10k put on a prepaid green dot card......
Automated call IRS, need to call immediately. Trust me, if the IRS is after you they won't do it by phone. If these scammers put the same effort in positive endeavors they would get richer quicker. This scam from Washington State (maybe). Got similar call a month ago from Texas, unless that number was spoofed too.
