CASH U, We cant buy RP fore more than 4 days !!!!

we cant buy RP throw Cash U for more than 4 days due to a bug in the "i am human" thingy

when you click i am human, it just keeps on loading !! doesnt show any quiz or let you confirm that you are human

i tried to reset my IE settings , contacted my ISP , and even changed my location nothing helped ..

i have tried to buy things with Cash u from another sites and the "I am human" worked fine with no problems so the problem must be from** Riot side **!!

PLEASE fix it asap because it gonna make us miss the skins discounts for jayce and ziggs !!
