It was a telemarketer for extended warranty on my car. I believe it was a robo-call with robo response. I told him I wanted to ask him questions. I asked for the name and address of the company on his paycheck. He told me National Repair Protection Services St Louis MO. I asked for the street address and got the dial tone. I have received more than 30 car warranty calls since August. I have put all the numbers on my blocked list on my Panasonic phone system. My number has been on the do not call list for over 6 years. This was an illegal call, as were all the others. But not one will give me full information about who is calling. Many are hang ups, probably due to auto dialers, some are solar marketing calls, some are credit card interest marketing calls, all from different numbers.
