Cannot cancel/renew membership due to auto-renewal payment fail

Hi!

I wish to cancel my adobe membership but can't seem to do it. I was unaware that my prepaid plan would auto-renew, so I didn't worry about cancelling it prior to the end of my plan. Adobe tried to take money out of my bank account (which is still my current bank account, so payment details are correct), but it failed due to insufficient funds. Now, when I try to cancel the plan by clicking "Manage Plan", there is no option to cancel or renew the plan: only to update my details. I cannot update my details, because they are correct (I guess when I click SAVE it doesn't update because there is still insufficient funds in the account), but I cannot cancel the plan either. I love these programs and want to continue using them, but the price my plan auto renewed to is $300 more than what I paid last year, and I feel like that might be an incorrect price and I can't afford it. I would just leave it and let the plan run out, but am concerned if/when I wish to purchase another plan that I will be unable to, due to an open invoice I can't pay for.

Any suggestions?
