Minecraft Parental Consent

So, I wanted to play Minecraft Realms with some friends, but I have to get a parental permission, so I did that and everything worked until you have to pay the 0,10 cents.

The credit card does work and I typed everything right, but still this error message appears: Credit Card information is wrong etc.

Is it a problem of their Servers or what? Could it be credit card issue?

Anyone managed to get their credit card to work with Minecraft stuff?
