I got the same call just a few minutes ago. I never answer unknown callers. He said is from the IRS. listened to the voicemail. The voice and accent reminds me of Nigerian scammers preying on dating sites. They upload pics of goodlooking men and women and say nice things. They would give local phone numbers but i checked and the numbers were actually bounced off to Nigeria. I told them i have reported their number to the FBI and they were gone and all the profiles they have created.
