Need to remove 4 unused Acrobat Team licenses

This is extremely frustrating. I have searched everywhere to find an option to remove 4 licenses of Adobe pro that are not being used and i cannot find the location to remove the licenses. I have called numerous numbers listed everywhere and even called the Mexico number since i am bilingual and cannot get ahold of anyone. I have tried to use the chat box but it keeps crashing asking me to refresh or reload the page. How difficult is it to add an option to remove unused licenses. We have a total of 17 and only using 13.
