I have had probably the same call 3 days in a row. I told him I didn't have time to do what he wanted me to and to have a good day and hung up. He called back the next day and my husband told him you called yesterday and the day before then he hung up. It is the same guy that called a few months ago and if we hang up on him he would call back.....he was rude and hateful...my husband told him he was a scammer and the guy called my husband a A**hole and hung up.
You just have to be smart and NOT fall for what they want...Don't let them catch you off guard.
