issues-with-unsubscribing-from-promotional-emails

I have two linked accounts for service at two different addresses. I had to use a different email address for the second account, and I cannot register my cell phone for the second account (error: "that email/phone number is linked to another account"). When I login to the second account, I cannot access any pages that allow me to control communications/turn off marketing emails. My "primary" account has all market communications turned off.

I still get marketing communications all the time, sent to the email of my second account. How do I stop them?
