Hello ArcKing,
What you are seeing are not charges, they are authorizations. Your card was being declined due to failing the address verification system. Usually this happens when the billing address attached to the card does not match what the bank has on file. Each attempt the bank was pinged. When this happens most banks will put a temporary hold on the funds, which can look like a pending transaction on your end. Because the card was declined we cannot finalize those authorizations (the 3rd, successful one is the only we can finalize). If not finalized authorizations expire and the holds are released. How long this takes is entirely up to your bank and not something we can control.
I have submitted authorization reversal requests for both authorizations. Your bank should be able to see them right away, but how long it takes to process them it up to the bank.
