If you have not received Pro after redeeming your Scribd code this is very likely because the Pro access went to an account you created beforehand or by accident via a different email address / different spelling of your email address. You typed Jane@email.com instead of email@example.com.
Our system is case sensitive so if you placed an uppercase somewhere when typing in your email address where it shouldn't be it will create a new account via that email address. Please try to log into your account minding the exact spelling of your email address the way you entered it when redeeming your code.
If this does not work, please send us your redeem link and we will be happy to help you with this!
