I called them back. "this is Michael from Senior Care, do you need a back or neck brace?"
I did stupidly join AARP a couple months ago, even though I am only 50. Stupid stupid stupid.
They must have given out my cell number to dozens of their "affiliates."
They did offer to hit 1 to order neck brace or 2 to be added to their do not call list. I hit 2.
We will see.
