troubleshooting denied payment

[JS]

We see that the guests card is denied on our pos. The guest sees that their card hasn't thru. They call up their bank account and show us where this transaction has gone thru their bank account.  What I saw on their bank statement: two pre-authorized charges for .01.  One charge for 25.22 and another charge for 21.22.  The total on the bill was 50.16.  Why does this happen?  it is very hard to convince someone that they haven't paid their bill when they see the charges on their account.

@JS It ultimately depends on how the customer's bank decides to display the charges to the guest. In cases where the card is declined, the charge may still appear as pending on the guest's account. However, these charges will eventually be removed since the transaction was not completed.
