Because my Hubby's name and our home number came up on the caller's ID when the phone rang, we answered the phone, and a woman was on the line. I asked her who she was, which she replied that she was calling from "Quality Control." She had asked for Mr. (our last name), and I asked her which Mr. would she like to speak to as I have sons. She replied that she wanted to speak to my husband regarding the interest on our Mortgage. I told her that he was not at home, and she replied that she would call at a later time. I asked her what number she was calling from and she gave this 415 number. We have not been answering the phone due to all these telemarketers and solicitors calling on a daily basis, which we are so tired of. Because the caller ID showed my husband's name and our phone number, we were curious and answered. This is so weird! How does this happen.
