Hello there, BNM.
Thanks for letting us know about this.
Since I want to make sure you are routed to the right support that can help you with GoPayment transaction cancellations, I suggest you reach out to our QuickBooks Merchant Support Team. They have the necessary tools to verify the status of the credit card transactions and investigate why you are being charge.
Just in case you'd want to know more about processing payments for credit card transactions, feel free to check out this link: Process a payment in Merchant Service Center.
Keep me posted on how it goes or if you have follow-up questions about this. Please know that I'm here whenever you need help.
