Tried to see me extended warranty insurance.  I don't need it.  I told the guy I was on the do not call list.  He acted like he didn't know what I was saying.  I then told him he was harassing me at work.  He still continued like he didn't know what I was saying.  I finally hung up on him.  I am blocking the number also.  He stated he was from USA,  I answered due to the fact I have USAA calling me in regards to an auto accident that one of their insurers hit me.
