Any credit card deposit that is returned to your bank (or “charged back”) will result in a partial blocking of the account. In those cases, you won’t be able to deposit with cards or withdrawal using any method until the issue is resolved.
When a chargeback happens, the funds are credited to your Galaxy account and possibly already used to place wagers, however, Galaxy never actually received the money. As a result, the software will make a manual account adjustment to remove the owed funds from your balance (if available).
In order for the account to be returned to good standing, with full access to card deposits and payouts, you will need to make a new deposit for the amount owed.
