Since IE worked for you, did you already process the payment or did you go back to Chrome and test it out before making the payment?
I processed my payment using IE, but did go back to chrome and retested with the same results, 28-Feb-17.
Now, today (10-Mar-17) I tested the 'Refill your account' and the payment method page displays properly.
It does not revert back to the account page after 2 seconds.
This issue appears to be solved.
That's great news!
Thanks so much for coming back and keeping us updated on this.
