I absolutely hate getting their letters and crap!!
True story here.. I was inundated with AARP crap once I turned 50 or 55 (can’t remember the exact timeline) and it went on for a couple years. I sent letters asking them to take me off their mailing list, emailed them to take me off their list, called them to take me off their list and finally filed a complaint with the BBB and said their tactics were harassment and threatening etc.
I received a letter asking me to call them (AARP) I contacted them and they asked me what they could do solve the BBB complaint and I said to take me off any mailing, email or calls list they had and make it permanent. The guy said “this may sound macabre, but if I put you in our system as deceased this will end all of the letters etc”.
I said “Consider me dead and make it happen”.
Took a couple months but everything stopped including all the AARP insurance crap as well.
