I've been dealing with these people off and on 4 bout five months. First time was with a male with the same story of reportly trouble in my area, told him no thanks my house is a fortess now, wouldn't take no for an answer tried talking over me so  I hung up. Have received approx. nine more calls always someone on the other end of the line who sounded like Oriental women on one occasion  I yelled how dd you get throught to me I am on the DNC list then I would get a quick hung up.  The end of March I said to the man that called again I have had enough of this I am a cop, the calls stopped untl yesterday.  Never though of calling FTC until finding this site so glad I did. PS. I am not a cop but it worked for almost 3 months
