You weren't invited to a simple shared folder. You were invited to and joined their Business account. When doing so, you merged your account into their team account, effectively making them the owner of your account. Prior to that you were given a choice to join the team and merge your account, or to move your personal files to a new account, separate from the team, and join the team with your now empty existing account. It sounds like you chose to merge your existing account and files into the team.
In order to leave the team, the team admin needs to convert your account back to an individual account. It's important that they don't just remove you from the team as doing so would delete your account. If that were to happen, the team admin only has seven days to restore your account. Also, only the team admin can get this done for you. Dropbox can't do it.
