Robotic voice of the IRS informing me that 6 lawsuits are pending against me for tax violations. Our local police department has an online crime/incident reporting service. I've filed a report to get the phone number into the police database. I also reported it to the Federal Trade Commission.
Two years ago I emailed both U.S. senators from my state complaining about spam telephone calls and the total ineffectiveness of the Do Not Call registry.  I got one reply in a week for one senator stating how proud she was in being instrumental in enacting the federal Do Not Call registry. The other replied after about six weeks. Nothing in her email mentioned spam calls. Just what a wonderful job she was doing in Washington.  I continue to get spam emails from her office even though I've have requested to be unsubscribed multiple times.
