You cannot come to a conclusion about worthiness or otherwise of your sponsor and co-sponsor, without subjecting yourself to the test below:
Your affiliate page is the perfect record indicating your strengths and weaknesses, in the form of badges you've earned.
Just check which are the badges you've not earned, compared to both your sponsor and co-sponsor. Ask them to guide you also to secure those missing badges, and I'm sure they will guide you.
That is how you commence a dialogue and get a satisfactory response. In my guess, no TL in SFI will ever disappoint his down-line member.
