Received a telephone message from Internal Revenue Services(?) that this is the Final Notice on a Wednesday night at 5:29 p.m. They are filing a lawsuit against me. They told me to call (202) 239-6007. This is no doubt a SCAM as the IRS (Internal Revenue Service) sends plenty of correspondence via mail about any owed debts. You would never receive a Final Notice at the last minute without notice. Also they would not call after hours 5:29 p.m. No mention of case number, just call that number.
