I'm getting constantly spammed with emails about riot accounts, despite already doing it

Hello, a week ago i updated my account to have a unique username for the riot account update, and whenever i follow the link to the site it says i'm all done. Yet i've just now recieved my 4th e-mail about needing to update my account to a Riot account (despite this already being done) and i'm starting to get tired of it.
