The majority of that mail is junk clearly designed to trick gullible old f@rts into signing up for various "services" that will cost them money.
Prescription drug plans, chronic-care plans, Medicare supplement plans, who-knows-what plans sending her documents that read at first glance like she has already enrolled and just needs to “update” some (personal, financial) information and sign on the dotted line. Trouble is, she hasn't enrolled in any of them. I'm the only person who can enroll her in anything or sign on her behalf, so I know.
These crooked corporations wouldn't send out so many of these misleading mailings of there wasn't serious money to be made. How they can look at themselves in the mirror when they profit from bleeding old people on fixed incomes dry I will never know.
Well, there is one thing I can do besides feeding this crap to the shredder. I file mail fraud complaints with the United States Postal Inspection Service.
If you have any impaired oldsters you care about, please check their mail. Watch their accounts and investigate any irregularities. And when you find fraud attempts, please take a moment to report them. Hopefully, if enough complaints are filed some of these scam artists may end up getting shut down.
