In a similar vein, don't be intimidated by scare tactics, particularly in robocalls. I have received recorded messages from "Amazon" telling me that I just bought a $1000 iPhone and alerting me to call back to verify. Caller ID, of course, shows a local phone number. In any event, Amazon does not call you, and a dead giveaway is that the recorded voice opens by saying "Dear Customer" instead of my name. And, of course, Social Security and IRS will NEVER phone you to tell you that your account is being suspended or that you owe back taxes.
When you get a phone call like these, the best thing is to hang up. Do not call back and vent your anger: That only tells the robocaller that your number is viable. If an actual person calls, don't waste your time in invective. As soon as the call ends, the scammer simply goes on to the next victim.
