Hello WarsWorth,
Your card is being declined because it is failing the address verification system. Usually this happens when the billing address attached to the card does not match what your bank has on file for it. What you are seeing are not charges, they are authorizations. Each time you tried to submit the order your bank was pinged to make sure the card is valid. 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. If not finalized, authorizations expire and the holds are released. How long this takes is up to your bank and not something we can control.
