Robot female voice stating second attempt to contact me to make an appearance before a grand jury. If I don't return the call, she says the only thing she can do is wish me a good luck in whatever falls upon me. Kinda bitchy and nasty. Called them back to yank their chain too. Claimed to be the US government's tax office. Even had a badge number! Said I owed money from taxes being filed incorrectly. I told them I always have my taxes done by a company that guarantees they are done correctly or they pay to fix it. He insisted that it was done incorrectly and I owed money. When I asked how much so I could tell my tax company he hung up on me. This is certainly a scam.
