This number calls several times a day, saying they are the IRS and threaten legal action if I don't pay. They leave auto messages, but answer "Internal Revenue Service" when called back. Background noises include daytime television, and lots of loud children. Apparently this scam has worked enough that they simply change the number when found out. It has been noted in the news that they have actually thieves money from people. It would be nice if they were prosecuted.
Scammer calling multiple times per day regarding an IRS lawsuit. There is no lawsuit. Ignore these. They are now using a computer generated voice to disguise their identity. Complete fraud.
