I assume by refute, you mean dispute. It does not matter that you have paid the balance, you can dispute any charge to your credit card that you wish. I have, for example, successfully disputed charges for merchandise that was ordered but never received after paying the relevant balance. US law requires that the bank accept and investigate any dispute filed within 60 days of the charge's posting date. Situations that involve charges that are older than 60 days will be at the discretion of the bank. You can always call up your bank and discuss your options. If you file the dispute, the bank will then investigate the charge and either decide in your favor or Delta's. Be careful disputing a charge stemming from an open ticket, Delta may just cancel the reservation when they are made aware of the dispute.

Turns out the agent that booked our new reservation "forgot" to put the voucher into the system. The new agent saw the credit card charge vs. what was in their computer. So they said we'll get it refunded to the card in 10-12 business days. By now that's a week from now. Let's hope so...
