Have you completed your switch?
If so, you can tap 'Help' > 'Ask WattBot' in your account and type "where's my amazon voucher" so this can get sorted for you
We also have an FAQ which may help!
And just FYI I've moved your post to our section all about referring friends and earning rewards, where there's lots of great help and info from other members :raisinghands:
