Priority Service Center has been sending very slick junk mail to my 92 year old World War II veteran father. They offer a very misleading (illegal?) advertizing package claiming the old man has the potential to receive millions in cash in the Australian lottery. All he has to do is send them $20 to claim it.
My father has been ripped off numerous times by this outfit. The old man has borderline dementia and can no longer distinguish between legitimate honest offers and this type of rip-off.
I filed a complaint against them with the Illinois Attorney General's Office (Consumer Protection Division). You may wish to do the same thing by writing to the Attorney General in your state for problems you have with these types of companies.
Add this company to your list of outfits to stay away from.
