Received a call from this number and I didn't answer. They left a voicemail it was some guy with a strong middle eastern accident and I couldn't understand most of the message. Stated something about being from the IRS Audit department and he was part of some alert group to call him at his direct line and 202-574-8801. I know it's a scam because I just talked to the IRS last week and they didn't say anything about it.
