I congratulate the affiliate. I always say "I am proud with you" and "I believe in You." I also thank the affiliate for the effort. I say that I am happy we're on the same team. In the end, I say "Keep up the good work" and "Contact me anytime. We will succeed together."
I only encourage them. I never pressure them to buy anything. The other thing I do is show them the most economical wat to earn their rank with the time they have left in the month.
