Your parental validation script is stuck in a DO Loop.

Trying to buy Minecraft Java for Mac OSX.  After half an hour wasted I have noting to show for the effort.

I have created an account for my son, run the parental verification loop, validated my credit card, and everything appears okay.  When I attempt to buy on my son's account it goes through the parental validation loop again, asking me for all the same repetitive data, I got a verification email, but then it asked me all the credit card info, thereby wasting my time.  What was the point?

Please fix. 

It's obvious it would have been easier to lie about my son's age than to got through your buggy and repetitive authentication process.
