In the mean time, to ensure all your memberships are cancelled - while online, click on the person icon> go to manage account> Now membership and then click on cancel membership.
There will be a few pages of "are you sure" and maybe an offer to keep you but keep clicking cancel until you get a confirmation message. You should also receive a confirmation email.
You need to do this with each active membership individually.
