I can't edit my payment plan

I cancelled my plan, and I didn't have enough money on my card to pay the early termination fee.

I have enough money on it now, and I received an email asking me to edit my payment details.

I followed this: Change or update your credit card and billing information in your Adobe ID account

Rather, I tried to! I got as far as step 2 and could not find the "Manage plan" option anywhere.

What am I supposed to do? I hope they don't charge me even more...
