If I cancel my membership, will my new sponsor be the sponsor the people currently under me?
Now if everyone who you sponsored did not get support. Then the process of membership change for support applies with them also. So being logical they would follow your lead to remain in your group. It is only fare if no upline support exist.
Take it one step at a time. Contact all your personally sponsored members, have them cancel and you do the same. Then after you account is not in 7 day free pre-view status. Then you make contact with your group to join utilizing your new link. Now, everyone is where they should be. Makes since now?
