Received call from 347-305-1237. It told me to call back at the same number concerning a arrest warrant. I called back and on person said his name was Keith Marshall Badge number 835110 of the US Marshall Office and said their was a warrant out for my arrest for unpaid taxes in 2012. I said what do I have to do to resolve the issue. The person than put me on a brief hold and patched me through another guy who said he works for the IRS he name was Brian King Badge number 8044891he than said I owe 4,898.28 in back taxes and the only way to stop the warrant was to have me get cash and send it buy some us note that he had to verify on the phone while I did this. I got suspecious and asked him where do I need to go get this so-called note to pay the IRS. He told me the nearest 7/11 store or walmart. I hung up the phone.
