Please can you elaborate on your post???
If you have not previously recruited 14 giffgaff members, you are not yet a Super Recruiter. You become one automatically when your 15th recruit activates their 15th sim.
The information about standard payback (for those with less than 14 recruits) is at https://www.giffgaff.com/payback
The information about super recruiters is at https://www.giffgaff.com/help/articles/whats-a-super-recruiter
