Has anyone had their merchant account disappear from their QBO account without their knowledge?

Hi martinfrith506, 

Welcome to the Community. Your merchant account holds important information that's designed to be accessible to you at anytime. I'll be happy to point you in the right direction so you can get the support you need. 

Based on what you've described, I see you benefiting more by contacting our support team outside of the Community. This ensures that your account info remains private and secure. Here are our contact details: 

• Schedule a Callback or start a Chat: click (?)Help in the upper right in QuickBooks Online > type and enter "Contact support" into the QB Assistant > click Contact Us > explain your situation > click Let's Talk > choose Get a callback or Start a Chat.
• Social Media: Facebook, Twitter, and Instagram.
• Support hours are from Monday to Friday between 9 a.m. and 8 p.m. ET.

Feel free to keep me posted on how you make out. I'll be one message away in case you need anything else.
