Hi there.
I'm here to help you get the best with changing the payment method of your Intuit QuickBooks Online account. Since you've mentioned you can't access your account right now, I recommend contacting our QuickBooks Online live support to request a direct call from them.
Here's how:
- Head to this link: Contact Us.
- Select QuickBooks Online product and click Continue.
- Select Contact Us and choose a way to connect with us:
- Start a chat with a support expert.
- Get a callback from the next available expert.
Moreover, you can also change your payment method directly in your QBO account.
I'd also like to drop this article to help you manage your Intuit account through CAMPs: Change, manage or update your Intuit account with CAMPs.
If you have additional concerns besides changing a payment method in your QBO account, feel free to reply below. I'd be glad to assist you.
