Missed calls today at 11:34AM EST and 2:59PM EST. Automated message to return call - no information, just the phone number. I returned call. The lady on the phone said she was with the Internal Revenue Service and the call was regarding a law suit being filed against me by the Internal Revenue Service. I refused to give her my information. Clearly phishing scam to gather names and SSN information.
Don't be alarmed. Relax. This is apparently a scam that is common during tax season. You can actually go on YouTube if they left you a voicemail and here the same voicemail.
