IF YOU ALREADY CONTACTED YOUR SPONSOR AND YOUR SPONSOR DIDN'T RESPONSE YOU, YOU CAN ALWAYS CONTACT YOU CO-SPONSOR OR OTHERS WHO ARE LEADERS IN YOUR TEAM, BUT THEY NEVER BE NON-RESPONSIVE ESPECIALLY IN SFI SPONSORS.
IF YOUR SPONSOR IS NON-RESPONSIVE YOU ALWAYS CAN SUGGEST ANOTHER SPONSOR, I THINK THEY DO HELP YOU TO FIND A NEW AND GOOD SPONSOR.
