Trying to buy Gems, keep getting Code:103

Trying to buy some gems to level up my characters, but I enter my info and it kicks me back a code:103
Purchase not completed please try again, tried the help desk folks and have yet to hear from them

Any ideas?

Hey Neokahrn, I’m sorry to hear that you are having trouble buying gems. Could you please check if the purchase information you have connected to your app store is correct? Try re-adding your purchase information and see if that helps.
