I also got a call from Officer Sean White from the IRS telling me to call this number back. Yes there was an accent but I could not identify but would not say British or Australian.
Do not call this number back, if the IRS was trying to reach you they would mail something first and the call would come from a line identified as such. Don't be stupid.
I also got a call from Shawn White stating IRS agent. After I asked who he was and what he wanted he replied by saying, "This is IRS and you don't talk to me that". I was a bit rude and I guess thats why our conversation ended by him saying, "Don't call here again stupid"
Got call from Shawn White from IRS, called back and it landed on a call center and the call got disconnected after they said i am charged for Tax crime. Called back and the guy claiming shawn white picked up and said i have to pay him through net banking. I suspect this as a spam call and asked him to go press charges
Got the same call from a supposed IRS agent - stating that it was a time sensitive legal matter and I needed to return the call immediately. This was from the most foreign sounding Officer Mike Jones I've ever heard of. I Googled the number and found this site --- I won't be returning that call.
