I got the same call. I guess I missed it because it came in September and I caught it while going through old voicemails. I knew it was total BS but I called back anyway just to see what they'd say. I got a voicemail asking me my situation so I could be moved to the top of the priority list. I hadn't even finished listening to his message before he called back. I told him I had received a message about a "Federal Investigation" and he told me he was sorry and that it was a mistake. I hope people don't actually fall for this stuff.
I also received a call from this number as well as other numbers with this same scam. I only seem to get them on my cell phone not my landline. I called the various numbers from my landline blocking my number- finally one them answered (i guess he dropped the ball so to speak). I informed him im in law enforcement and if he does not stop calling me i will have him tracked down and arrested. I heard nothing on the other end so i hung up. I guess he finally got the point. Also had a heavy indian sounding accent.
Just received the same message from a man with thick stating it was an officer with the irs calling for tax evasion. Left a message to call. I texted to the # that called that he was being reported to the authorities
