UPDATE: Thanks again for raising this issue hrudham. It seems there is indeed a bug in the current unsubscribe flow. This was not intentional behavior, and it will be corrected. As for "30 day" period, my initial review indicates this should take 24-48hrs max to be fully unsubscribed (based on how our email and account systems interact). Working on getting fixes for everything. Will update again once it's all corrected.
