I got your back in ensuring that you'll be able to delete the credit after customer issued a refund in QuickBooks Online. 

Here's how to delete or void credit: 

1. Click Accounting then select Chart of Accounts.   
2. Tap the View register of the bank account associated.
3. Select the transactions you want to delete. 
4. Choose Delete and then click Yes.
