Sorry you are having trouble! Unfortunately accepting cards is mostly up to the credit card processing companies and your bank. I see your first 3 attempts failed with the reason, "The customer-entered zip/postal code does not match the code on file with the card-issuing bank." Then the 4th attempt failed with, "The bank returned the decline code do_not_honor." I guess you'll have to contact your bank and ask them, 1) what postal code should you use, and 2) to make sure they don't block the transaction.
