Started getting a call every day between 9 and 10am for about 3 weeks.  Albany, LA - caller ID number varied by as little as 1 digit.  Finally answered, it was a male voice, no accent.  He asked for a person not in our household.  When I told him there was no one here by that name he asked, in a demanding tone, if I was related to or knew them.  He became agitated when I questioned why in the world I would know who and where this person was when I just stated he had the wrong number (several years ago we changed landline carrier and acquired current number and started receiving calls for that other person).  I clearly let him know I was very unhappy about the repeated calls and that we had been watching the call time and number cycling pattern, asked him what he was calling about and he stated "he couldn't say" and that "he was a consumer too".  Man said number would be removed and we have not received a call from 225-500-00xx in the past three days.
