I appreciate you for connecting with us here, @cajunsouthservic. Know that this isn't the kind of experience we want you to have. Since this has been happening with more than of your customers we suggest contacting support again to be added to the investigation.
I'll guide you to the best way to contact the right person to get the help you need.
To speak with one of our experts, you'll want to go to this article: QuickBooks Merchant Support Team. You may scroll down to the bottom part of the article to see their contact information.
I'd recommend reviewing some of our commonly asked payment questions through this article: QuickBooks Payments FAQ.
You can contact us from Mondays to Fridays, 6 AM to 6 PM PT.
Feel free to drop by the Community whenever you have further concerns regarding your invoices. Stay safe!
