Fizz can't figure out missing referral bonuses. Is everybody's Fizz referral bonus all hit and miss?

I like Fizz's features and referred some friends. They jointed and told me they love it. And I found out quite a few bonuses are missing. They use my code to register account, and use it again to activate sim card. Still missing !
Just want check if it's just me, or somebody else too.
Why not Fizz make it easier, use that code to register account and I can be qualified for the $25. Or use this code to activated sim card will qualify too. Now Fizz made BOTH required ,and still missing !!!
Also the whole process is so complicated for a non-teksavvy users. Why not Fizz find some sim distributors locally and let them distribute SIM cards and do activation, as return, give these distributors referral bonus as return. It's a win-win situation. Fizz management should serious consider my suggestion.
