Trying to purchase RP bug

Once I select an RP amount, a few strange things have happened.

1. Can't delete any saved card information
2. Without any input, it will randomly say "invalid cvv".
3. The most frequent problem, is the cvv entry bar wont even show up, and the 'pay now' button is blank and off center.
4. Anytime a purchase is attempted, it just says "you've encountered an error". I've tried restarting the client and nothing changed. This sucks because I really want the new Yasuo skin. :'(
