Same thing happens to me except it's Sophia (I am a dude)

Every October I get a hundred or so calls and texts for someone named Eileen reminding her it's open enrollment time for Obamacare. It started suddenly a few years ago so I think the real Eileen just entered the wrong number by mistake but I have no idea how to make it stop.

Surely you must be joking.

I'm serious and don't call me shirley.

I get messages for Katherine, who has not had this phone number in at least 15 years.
