OpenAI is charging me a monthly invoice after switching my plan to credits only

Recently I recieved an email which stated:

"We’ve updated the billing system for your OpenAI API account. Instead of receiving a bill at the end of the month, you’ll now need to pre-purchase credits to use the API. This change should enable you to access higher usage tiers more quickly. "

So I topped up the account with credits to cover the balance for this month.

However I just received an email stating that:

We were unable to process your last payment for xxxx using your card. We’ll try to process your payment again in a few days. If we aren’t able to complete your payment by Apr 10, 2024 12:00 PM UTC , your organization’s API access will be suspended?

Why did my top up not clear the outstanding balance, I have an invoice in an open state for this month, for the amount of the outstanding balance - hence I am being billed twice?
Why am I still getting monthly invoices after being switched to a credit plan?

Hi there! Open balances from under the old billing model can‘t be paid with new credits. You still have to provide a valid credit card to pay for the open charges. If you are facing specific issues in this regard, then it is best that you reach out immediately to OpenAI support via the chat widget in the developer platform.

Can you direct me to where I can access the chat widget? I cannot find it.
