changing merchant center phone number

Let me help you with this, @SueMcA.

If you're unable to access your previous phone number that is associated with your account, it'd be best to reach out to our customer support. This way, they can update your phone number to make sure you're account's information is updated.

You can click this link to reach out to them: Contact QuickBooks Online with Payments & Merchant Service Center.

In case you have questions about the security of your Merchant Services account, you can check out this article: Access your Merchant Services account FAQs.

Don't hesitate to tag my name in the comment section below if you have other concerns or questions. I'm always ready to help.

When I follow your steps it does not have a lets talk button to click.
