RotMG Payment Methods

Hey guys, I'll cut to the chase...

Today I went out and bought some Subway cards so I could purchase some Realm Gold (yes previously they worked, used them many times). When I get back home, I hopped on Realm and tried purchasing some gold.

The option to use Gift Cards is no longer there from what I can see.

Fuck me.

If anyone knows anything about this or whether or not I can still use these cards, I would greatly appreciate the help.
