Partial Credit Card Payment

Weird occurance here for us-

• Customer paid $1000 with a Check card(debit/Credit)
• Payment gateway returned partial approval for $7XX.XX
• Tessitura showed a partial amount payment, $7XX.XX
• Box Office refund attempted for $7XX.XX and Box Office received the FABULOUS EMV /s error
• Box Office posted back payment of $7XX.XX instead of refunding
• Payment Gateway posted $7XX.XX back as a CreditCardCredit
• Contributions screen froze on the Box Office, had to brute out of tessitura
• 14 days later - Gateway returns partial sale for remaining amount of $2XX.XX

All of this and there are NO traces of the payments/transactions in Tessitura that I can find.

Does anyone have any idea about how I can find the actual amounts charged and what I can do to correct this for reporting in Tessitura?
