I also got call from this number posing to be from IRS...!! .they are not the IRS, but a SCAMMERs!
Remember, NO ONE from any US Government offices will call to demand money from anybody, legitimate US Government business should be in writing, you must always verify first before giving any information or money
IRS scam. Beware, these are the worst kinds of people. No number bounce, the number works for callbacks as well. Probably originating from India/Pakistan.
