I answered the phone, the caller id also said "intl. number", the woman asked to speak to Teresa. I asked Teresa who they also gave me a last name. This was strange because the name they gave was that of my father's girlfriend. However the call was to my Mother's house...I told the caller she did not live here and to not call again, but as you know the calls have not stopped. They have even begun calling at all times of the day. I've seen the number as early as 5 am!! I've tried to call back but there is no answer when I call. Hmmmmmmmm....
