Award Processing Center Can't get away from them Kansas City, Missouri

My father is 85 years old and for the last year or more has been receiving 40-50 pieces of mail per day.  Most of these pieces are either requests for money or these outrageous sweepstakes claims.  A few times he has even received telephone calls where the person called quoted sayings from the Bible and convinced my father that he had won $2,000.000.00.  All he needed to do was to send him $1500.00 to a contact out of the country.  Supposedly this was for a mission.  It turned out to be a scam, a number of people in the town received similar telephone calls.

I live in VA and my father in PA.  I can't be there to monitor his mail and I want him to have the independance to make decisions for himself but being inudated day after day by these offers would cause any of us to start to get a little upset. 

I have contacted the PA Attorney General about the first incedent but there have been at least 2 others that I know of.  We have tried to change the telephone number but these scam artists have been able to locate it again.

I don't know what happened to the privacy of one's own home.  How are these people able to get the information and keep badgering our seniors?
